Abstract

This paper presents an approach for improving the Quality of Service (QoS) of CDMA systems based on the proposed switch coding scheme at the encoding process of transmission and a bandwidth scheduling scheme for achieving high throughput services in multi-rate CDMA system. The paper presents a bandwidth scheduling scheme based on the available resources depending upon the demanded service bandwidth. To avoid the Multi-access Interference (MAI) due to simultaneous requests a code switching scheme is proposed. The QoS metrics were evaluated for the developed system and compared with the conventional approach.
