A communications system of the present invention includes a transmitter that is operative for combining an orthogonal Walsh modulation with a minimum shift keying or Gaussian minimum shift keying waveform to form a hybrid communications signal that carries communications data over a constant amplitude waveform that is spread in time and frequency. This communications signal can be transmitted to a RAKE receiver that has a plurality of correlators with output weights formed for processing this hybrid communications signal.

The demodulator may include a channel estimation module for generating respective channel estimates for a prior unknown symbol portion(s), current unknown symbol portion and for future unknown symbol portion(s). An autocorrelation module may generate autocorrelation matrices for the prior, current and future unknown symbol portions. A channel match filter module may generate respective channel matching coefficients for the prior and current/future unknown symbol portions, and a factorization module may divide the autocorrelation matrices into respective upper and lower autocorrelation matrices. A transformation module may transform the channel matching coefficients into upper and lower channel matching coefficients. A a back-substitution module may determine the current unknown symbol portion based upon the upper and lower autocorrelation matrices and channel matching coefficients for the current and prior/future unknown symbol portions.

A wireless communications device may include a wireless receiver receiving signals having alternating known and unknown symbol portions over a channel, and a demodulator systolic array. The demodulator systolic array may include a channel estimation module generating respective channel estimates for each unknown symbol portion based upon the known symbol portions. An autocorrelation module may generate autocorrelation matrices based upon the channel estimates. A channel match filter module may generate respective channel matching coefficients for the unknown symbol portions, and a factorization module may divide the autocorrelation matrices into respective upper and lower autocorrelation matrices. A transformation module may transform the channel matching coefficients into upper and lower channel matching coefficients. A back-substitution module may determine the unknown symbol portions by estimating the unknown symbol portions based upon autocorrelation matrices and channel matching coefficients, lower autocorrelation matrices and channel matching coefficients, and combining the estimates.

A system communicates data and includes an encoder for encoding communications data with a forward error correction code. A data randomizer randomizes the communications data with a random bit sequence and a combining circuit combines the communications data with known symbols into frames. A modulator maps the communications data into minimum shift keying or Gaussian minimum shift keying (MSK or GMSK) symbols based on a specific mapping algorithm to form a communications signal having an MSK or GMSK waveform over which the communications data can be transmitted.

A communication system includes a plurality of nodes forming a wireless mesh network. A plurality of wireless communication links connect the nodes together. Each node is formed as a communications device having a physical layer and a media access control (MAC) layer in accordance with the Open System Interconnect (OSI) model and operative for transmitting and receiving communications packets to and from other nodes via the wireless communication links in an Automatic Repeat Request (ARQ) mode. The physical layer monitors channel parameters of the wireless communications link when in an ARQ mode and, based on the channel parameters, communicates to the MAC layer over-the-air (OTA) parameters used for transmitting packets.

A communications system may include a first communications device that may include a transmitter and a modulator cooperating therewith to modulate a coded waveform using a constant phase modulation (CPM) to generate a non-linear CPM waveform, and generate a linear representation of the non-linear CPM waveform, the linear representation including a plurality of pulses. The transmitter and a modulator may further cooperate to remove at least some of the plurality of pulses to define a modified linear representation of the non-linear CPM waveform, and transmit the modified linear representation of the non-linear CPM waveform. The communications system may further include a second communications device that may include a receiver and a single pulse-matched filter linear demodulator cooperating therewith to demodulate the modified linear representation of the non-linear CPM waveform transmitted from the first communications device.

A device and method for controlling HF single side band radio squelch operation in which a serial tone burst indicates the start and end of a transmission and identifies an on-going transmission. Additionally, receivers in a power saving sleep mode can be activated by receipt of a set of serial tone bursts that have been transmitted with sufficient duration for the receiver to be assured the opportunity to detect them. During the subsequent transmission of information, single "keep-alive" serial tone bursts are transmitted at random time intervals. The end of a transmission is signalled by another set of serial tone bursts. The bursts are provided with the transmitted signal on its frequency and preserve signal bandwidth.

A method for compressing a short message includes receiving a short message that includes a plurality of text strings for compression, dividing the short message into one or more sub-blocks, where a number of text strings in each of the one or more sub-blocks is less than or equal to a predetermined number. The method also includes compressing each of the one or more sub-blocks by identifying a type of a first text string, identifying a code representing the type, determining whether the first text string exists in a library, upon determining that the first text string exists in the library, determining an index corresponding to the first text string, extracting a predetermined number of least significant digits of the index, and replacing the first text string in that sub-block with the code and the extracted predetermined number of least significant digits of the index.
