Various Diversity Combining Techniques with LDPC Codes in MIMO-OFDM

Naveen Kumar, Arvinder Pal Singh Kalsi

OFDM with MIMO is the most efficient and commonly used technology. In MIMO system multiple antennas arrays used across transmitter and receiver side. OFDM with MIMO technology provide reliable communication and efficient manner of signal reception across receiver. In MIMO technology Bit rate error very high due to Multi-path fading effect of channel. In this paper new technique is proposed to reduce Bit rate. The proposed technique uses LDPC filter with OFDM along diversity methods. LDPC filter is used in OFDM to reduce bit rate error and calculate performance in terms of BER for receive combing technique such as MRC. Since MRC provide excellent reduction in BER as compare to SC and EGC. The proposed technique is implemented in MATLAB and result shows that proposed technique will reduce bit rate error in MIMO-OFDM.

Keywords: Orthogonal frequency division multiplexing OFDM, multiple input multiple output MIMO, Low density parity check LDPC, maximal ration combining MRC, equal gain combining EGC, selection combining SC
