13.1 Introduction

 

Spread spectrum signals typically refer to signals that use a bandwidth that is significantly higher than the minimum bandwidth required to transmit that information sequence. Although bandwidth is a precious commodity, increasing the bandwidth of the signal prior to transmission results in several advantages: (i) The resulting power spectral density (PSD) of the ...
