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 Eb/N0 for producing acceptable quality voice
