Link protocol based on DS-CDMA with MUD for decentralized all-connected wireless network

To fulfill the application of wireless network in small area, this paper proposed a protocol for decentralized all-connected wireless network. This protocol is based on DS-CDMA with the ability of multi-user detection (MUD). And it has the characteristics of transmitting data in parallel, high network throughput and low communication error rate. In this paper, the process of the protocol is introduced, and an improved quasi-synchronous decorrelation multiuser detection algorithm is deduced in detail. And then, the protocol is simulated and the results are analyzed.
