Spreading code protocol enabling programmable complexity/performance for CDMA local wireless networks
The paper introduces a novel spreading code protocol, the adaptive group-receiver code protocol, offering flexibility and stability under varying traffic conditions. In the protocol, terminals are divided into groups co-ordinated by central stations and a group-based receiver spreading coding is used to manage the contention among users in the groups. The protocol can adaptively adjust the number of groups according to traffic load and throughput–delay requirements. The analytical results show that the protocol is particularly befitting for the applications in local wireless networks requiring high throughput and low access delay.
