This study derives the reverse-link capacity of anSIR-based power-controlled multicode CDMA system supportingheterogeneous CBR and on-off traffic in a multiple cell environment.Mean and variance statistics of total other cell interference, and theeffects of traffic and propagation parameters on system capacity areinvestigated 收起
