METHODS AND APPARATUS FOR REDUCING DISCRETE POWER SPECTRAL DENSITY COMPONENTS OF SIGNALS TRANSMITTED IN WIDEBAND COMMUNICATION SYSTEMS

摘要

Methods and apparatus for reducing discrete power spectral density (PSD) components of wideband signals transmitting blocks of data are disclosed. Discrete components are reduced by acquiring N symbols of pseudo-random data, each symbol having K bits; selecting one bit from each of the acquired symbols to generate N selected bits; selectively inverting a respective element in one of the data blocks responsive to the selected bits; acquiring one or more bits of pseudo-random data to replace a corresponding one or more respective bits of the acquired N symbols of pseudo-random data; and repeating for successive blocks of data.
