|摘要:||The development of a high-throughput and low-cost medium access control (MAC) layer design is a very important issue for wireless local area network (WLAN) communication. In this paper, the proposed MAC-layer hardware architecture is simplified by using a small number of finite state machines (FSMs) and a low-latency parallel processing architecture. The FSMs on both the transmitter (TX) and receiver (RX) sides can be operated at low power. In the MAC-layer receiver, an efficient low-complexity timestamp controller is proposed for fast timing synchronization. We implement the distributed coordination function (DCF) of the MAC protocol in IEEE 802.11a/b/g standards within the ad-hoc configuration. The proposed MAC-layer hardware is implemented with Xilinx XC4VLX60 FPGA, the hardware area needs 5944 slices, and the effective throughput is 147.6 Mbps. With TSMC 0.18 mu m CMOS process, the effective throughput at the maximum working frequency 83.3 MHz is 299.88 Mbps, which is larger than the standard IEEE 802.11 g requirement, i.e. 54 Mbps.|
