Abstract

A recently reported signaling system called OWSS (orthogonal wavelet spread spectrum) appears to have significant bandwidth advantage over the familiar OFDM. Moreover, this new technique has been shown to readily extend to high rates, such as 108 Mbps, in a bandwidth efficient manner. This paper discusses a CSMA/CA protocol for the MAC layer of packetized 108 Mbps OWSS, including the selection of key parameters, in order to provide full rate shared access to bursty users. Presented also is a theoretical model for performance analysis which indicates a saturation throughput of 66 % and an average packet delay of 5 ms using RTS-CTS - for a moderate number of stations.
