Abstract

The performance of a code-division multiple-access (CDMA) cellular system for different RF modulation techniques, such as quadrature phase-shift keying (QPSK) and differential phase-shift keying (DPSK), is analyzed. The analysis emphasizes how voice quality deteriorates with increasing system load and determines the maximum acceptable load and minimum acceptable E_b/N₀ for producing acceptable quality voice
