Abstract
In this paper, we consider an integrated voice and data system over CDMA Sl otted-ALOHA (CDMA S-ALOBA). We investigate its performance when multi-code CDMA (MC-CDMA) is applied as a multi-rate scheme to support users which req uire transmission with different bit rates. Two different classes of data u sers are transmitted together with voice. Performance measurement is obtain ed in respect of throughput for data and outage probability for voice. More over, we consider the Modified Channel Load Sensing Protocol (MCLSP) as a t raffic control to improve the throughput of data. As a result, we show that the MC-CDMA technique is an effective one to obtain good throughput for da ta users at an acceptable voice outage probability. Furthermore, we show th at with MCLSP, the throughput of data can be improved to reach a constant v alue even at a high offered load of data users.
