Abstract :
The quest for higher spectral efficiency in wireless communications 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 spread-spectrum system
