Viterbi Decoding Strategies for 5 GHz Wireless LAN Systems

Date: January 2008
Type: White Paper
Rating: (0)

Overview: This research paper explains the standards for the operation of Wireless Local Area Network (WLAN) technology in the 5 GHz band have been developed in Europe, North America and Japan. These systems employ Orthogonal Frequency Division Multiplexing (OFDM) technology, and utilize Forward Error Correction (FEC) coding, based on a 1/2-rate convolutional encoder, to combat frequency selective fading caused by multipath channels. This paper from Institute of Electrical and Electronics Engineers examines methods, based on the popular Viterbi algorithm, for Maximum-Likelihood (ML) decoding of this convolutional code within the WLAN baseband receiver.
