Abstract
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.
