超带宽无线通信中高速纠错编码硬件电路设计

High speed correct coding designing for ultra wideband in wireless communication

超带宽(Ultra Wideband,UWB)系统具有高传输速率、低功耗、低成本等独特优点,是下一代短距离无线通信系统的有力竞争者。维特比(Viterbi)译码性能优越,在允许全并行情况下实现高速传输。文章研究并实现了一种Viterbi码在AWGN信道和基于OFDM调制的超带宽系统中的应用。

Ultra Wideband （UWB） technology has the virtue of very high data rate, low power consumption and low cost, which makes it a promising technology for next generation short range wireless communication. Viterbi Codes achieve excellent error performance and permit fully parallelizable high speed decoding. In this paper we investigate and implement the performance of a Vlterbi code under AWGN channel and Ultra Wideband channels with those of convolution coded system.
