Description: A multiple-input multiple-output (MIMO) communication system combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable
high data rate transmission over broadband wireless channels. Channel state information for both single-input single-output (SISO) and MIMO systems based on pilot aided arrangement is
investigated in this paper. The estimation of channel at pilot frequencies with conventional Least Square (LS) and Minimum Mean Square (MMSE) estimation algorithms is carried out
through Matlab simulation. The performance of MIMO OFDM and SISO OFDM are evaluated on the basis of Bit Error Rate (BER) and Mean Square Error (MSE) level.-A multiple-input multiple-output (MIMO) communication system combined with the orthogonal frequency division multiplexing (OFDM) modulation technique can achieve reliable

Description: Orthogonal frequency division multiplexing (OFDM) has been proved as the dominant modulation technique for 4G communication. The use of relaying improves the BER performance of OFDM system. In this paper the BER performance of AF relaying with average power constraint (APS) is derived for an OFDM system. Also how frequency diversity scheme improves the BER performance in single antenna AF relay based OFDM system is discussed properly. Platform: |
