A transmitter includes an oscillator that generates a clock signal and a mapping unit that maps received data-bits to symbols and designates each of the symbols as three or more signal coding levels, where each of the signal coding levels are represented by a plurality of digital codes. The three or more signal coding levels representing each symbol are DC balanced and include a plurality of peak amplitudes. The transmitter further includes a digital to analog convertor that converts the plurality of digital codes to a corresponding plurality of analog amplitude levels at a rate determined by the clock signal, whereby the analog amplitude levels generate a signal coding level. A filter then smoothes the plurality of analog amplitude levels and generates a modulated carrier wave that is coded by the symbols.

A carrier state modulator system is described in which a stream of digital data bits is encoded by modulating the amplitude or phase of a carrier wave. A transmitter modulates the amplitude of a selected number cycles of the carrier in accordance with the state of each digital data bit. A receiver decodes the carrier state modulated signal by determining a phase score for the specified number of cycles of the modulated signal, the phase score based on a number of samples of the amplitude on a positive side of each cycle of the modulated signal that is above a selected amplitude and a second number of samples of an amplitude on a negative side of each cycle of the modulated signal that is below the selected amplitude. The value of the encoded digital data bit of the modulated signal is determined from the phase score.

An apparatus and method of compensating for systematic electro-magnetic distortions of generated and transmitted amplitude coded sinusoidal waveforms, where the distortions arise from the varying rate of change of these waveforms. An analog waveform is formed as an interference pattern generated by the combination of at least three substantially sinusoidal waves and represents input data which is divided into N-bit data segments, where N is an integer greater than one. Each of the substantially sinusoidal waves has at least one controllable wave characteristic which is controlled as a function of an N-bit data segment. The analog waveform is delayed through each of at least two delay paths having respective time intervals and respective weightings associated with each of the at least two delay paths are determined. A weighted delayed analog signal is generated at each delay path by multiplying each of the delayed analog signals by the weighting associated with that delay path. The weighted delayed analog signals from each of the delay paths are then combined to generate a compensated analog waveform to correct for electro-magnetic distortion in the analog waveform.

Digital data is encoded into a series of analog waveforms, called symbol waveforms, created as the result of interference of sinusoidal wave interference patterns. Each of these symbol waveforms is an encoded version of N-bits of data. These encoded symbol waveforms is an encoded version which are very different, in both appearance and in propagation properties, from traditional voltage state signaling or pulse codes. The encoded symbol waveforms are formed by generating and superimposing a set of analog sinusoidal waves, where the gain and phase shift of each wave is computed so as to provide, in combination, a unique interference pattern that can be recognized, via signal processing techniques, by a detector and then decoded. The symbol waveforms are computed so that successive symbol waveforms seam together to form a smooth continuous AC analog signal that does not itself generate interference frequencies, can be bandpass filtered, and is suitable for long distance propagation. The transmission technology of the present invention is applicable to, inter alia, a digital communications device or system.

A receiver apparatus adapted to be synchronized with a link transmitter to identify and isolate a transmitted, modulated carrier signal from other RF transmissions by obtaining A/D samples at each integer pi zero crossing of a transmitted signal and at the half Hertz cyclesof the modulated carrier signal. The integer pi A/D samples are at the carrier signal zero crossings and thus contain only the other RF and noise in the receiving antenna. The half Hertz cycle A/D samples contain both the carrier signal and the other RF being received at that instant. The analytical methods of the invention use the integer pi A/D samples to compute estimates of the other RF in the half integer pi A/D samples in order to separate it for the detection of the transmitted signal, thereby benefiting narrow band signals with constant zero crossing that are directly coded on the carrier frequency as DC balanced symbols, and enabling higher data rates than are typically achievable by passband filtering the receiving antenna waveform.

A carrier state modulator system is described in which a stream of digital data bits is encoded by modulating the amplitude or phase of a carrier wave. A transmitter directly modulates the amplitude or phase of a selected number of cycles of the carrier in accordance with the state of each digital data bit. This method of direct generation of an amplitude or phase modulated carrier wave differs from mixing a phase amplitude baseband modulation onto a higher carrier frequency.

A frequency specific receiver and method can receive a transmitted polarized carrier signal wave, the carrier signal wave having a carrier frequency, encoding one or more data bits, includes a synchronization filter to determine a reference time at 0π of the carrier signal wave from a forward wave received at a forward antenna element and a rear wave received at a rear antenna element, positioned apart from one another by a distance of wavelength of the transmitted carrier signal wave and oriented in a polarization direction of the transmitted carrier signal wave. A first A/D converter samples the forward wave at π/2, π, 3π/2 and 2π radians and a second A/D converter samples the rear wave at π/2, π, 3π/2 and 2π radians. A control processor decodes a value of the encoded data bit by calculation of an average computation and a calculation of a correlation computation.
