In the paper a spreading code protocol (the code-sensing R3 code protocol) designed for wireless local networks is proposed and its performance is analysed. In a network adopting the protocol, destructive collisions among terminals are minimised by utilising the busy code-sensing and dual chip-rate techniques in transmissions of the REQ and ACK/data packets. A two-dimensional continuous-time Markov model is applied to study the behaviour of the protocol. The results show that a respectable improvement in throughput-delay performance can be achieved by the proposed protocol when compared to those previously reported in the literature
