This paper examines antenna diversity combining system using the Maximal Ratio Combining(MRC) as a combining method and Channel State Information(CSI) Viterbi decoding strategy combined with the antenna diversity technology to overcome frequency selective fading caused by multipath channels. Also we investigated estimated CSI by using 2 consecutive long codes in the PLCP preamble for Viterbi decoding algorithm. The proposed new decoding strategy outperforms over a single antenna system and gets additional gains over a non-CSI antenna diversity combining receiver.
