摘要：

A Walsh Coded OFDM system is described which could provide an alternative to convolutional coding in packet based wireless LAN systems. This allows lower complexity decoding and lower peak-to-average power ratios. This system is compared with a hard decision decoded convolutional receiver, based on the OFDM specifications for the IEEE 802.11 and ETSI HIPERLAN/2 physical layer standards. In multipath environments, the high diversity Walsh Coded OFDM system shows large improvements over uncoded systems and similar performance to the more computationally complex convolutional receivers.
