Abstract

A simplified analysis is presented for the reverse link capacity of DS-CDMA mobile radio with transmit power control (TPC) based on measurement of signal-to-interference plus background noise (SIR) when users require different levels of quality. The link capacity is defined as the maximum achievable sum of the required SIRs, and the increase in transmit power due to SIR-based TPC is discussed. Also analyzed is the total link capacity when narrowband DS-CDMA systems share the radio spectrum of a wideband system. The capacity loss due to non-uniform use of the spectrum is discussed.
