Abstract : In the current paper, we have developed a new frequency offset estimation algorithm using cyclic prefix (CP) without using the training sequence. specifically for wireless local area network (WLAN) systems typically operating at 5 GHz radio frequency (RF) band such as IEEE 802.11 class of standards like 11a, 11g, 11n, 11ac and more recent one such as 11ax which is yet to be ratified, And are built on multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM). Rayleigh fading effects are applied in addition to additive white gaussian noise (AWGN) to analyze the performance. The algorithm performance is prevailed in all the MIMO configurations proposed for (2×2), (3×3) and (4×4). Also, it is observed that the mean square error improves as the configuration increase.
