Abstract:
Systems and methods for increasing audio SNR in a NICAM digital sound decoder are provided. One method according to the invention includes receiving a scale factor that indicates a number of bits of a Near Instantaneous Companded Audio Multiplex (NICAM) signal that have been truncated from the signal. The method also includes receiving the NICAM signal itself. The NICAM signal may include a predetermined number of zero bits in place of the predetermined number of truncated bits. The method may also require appending a bit pattern to the NICAM signal that approximates a rounding of the NICAM signal. The bit pattern preferably includes at least one non-zero bit. Another method according to the invention may include selecting a bit pattern from a collection of bit patterns. The collection of bit patterns may include at least non-zero bit. The alternative embodiment of the invention may also include appending the selected bit pattern to the NICAM signal in order to replace a predetermined number of truncated bits.
