Title
Optimal SIR for an hybrid cellular DS-SFH CDMA system
Abstract
A hybrid direct-sequence-slow frequency hopping code-division multiple-access (DS-SFH CDMA) system operating in a Rayleigh fading environment is described and its spectral efficiency is estimated in terms of the theoretically achievable average channel capacity (in the sense of information theory) per user. The analysis covers the operation over a broadcast cellular time-varying link and leads to a simple novel closed-form expression for the optimal average spread signal-to-interference power ratio (SIR) received by each user based on the maximization of the achieved spectral efficiency.
