is creating a new impetus for selective and sensitive
base-station receivers. One consequence of high selectivity
is phase dispersion, which critically affects the operation of a
phase-modulated communications system. If phase equalization
is not used, increasing selectivity will eventually compromise the
performance of a receiver. These performance limitations are
examined in a coherent and noncoherent direct-sequence spreadspectrum
system.
