In this paper, an adaptive detection technique for MIMO-OFDM system is proposed. To execute the adaptive detection, existing SMLD technique is considered. The proposed technique selects proper values of V of the SMLD scheme to each subcarrier according to its estimated received power. To estimate the received power, two estimation modes are presented (noise value estimation mode with a preamble and...
In this paper a non-iterative rectangular-type pilot-aided channel estimation algorithm on mobile multiple input-multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems is proposed. After minimum mean square error (MMSE) estimation in time direction, channel interpolation must be performed in frequency direction. Recent DFT-based algorithms, in MIMO-OFDM systems, reduce additive...
