摘要 文章给出了一种应用于移动多媒体通信的无线媒体接入控制(MAC)协议。该MAC协议采用混合TDMA/CDMA结构,以提高资源利用率;采用多码并行传输提供可变速率,以支持集成多媒体业务。系统仿真表明,该协议具有较高的码利用率和良好的灵活性,适用于可变速率多媒体业务集成传输。 This paper presents a wireless communications. The MAC protocol adopts hybrid medium access control(MAC) protocol for mobile multimedia TDMA/CDMA structure to improve utilization efficiency of resource, and provides various bit rates needed for integrated multimedia services by using multiple spreading codes. Simulation results show that the protocol is both efficient and flexible, suited for carrying variable bit rate multimedia traffic.
