A general scheme for spectral efficiency evaluation of direct-sequence spread-spectrum systems.

A general scheme for spectral efficiency evaluation of direct-sequence spread-spectrum systems.

Typically, spectral efficiency, the throughput in bits/second/hertz, has been evaluated for fixed values of the bit error probability. We introduce a cutoff-rate-based approach to evaluation of the spectral efficiency of direct-sequence spread-spectrum schemes so that the results are independent of...
