Paper Title
PEAK TO AVERAGE POWER RATIO and BIT ERROR RATE reduction in MIMO-OFDM system using LOW DENSITY PARITY CHECK CODES over Rayleigh fading channel
  Punit Upmanyu,  Saurabh Gaur

With the evolution of the wireless system in the demand for high-speed data have been increasing day by day, making it impossible to be achieved by the data transmission system in the conventional series, the quality of service and the other the need for additional spectrum in a limited spectrum scenario. To overcome this new system for data transmission problem in parallel has been proposed, which is known as the OFDM system. Performance of the OFDM system can be further improved by using multiple antennas in an arrangement called a MIMO system. MIMO-OFDM system is currently recognized as one of the most competitive technologies for 4G wireless mobile systems .The main disadvantage of MIMO-OFDM system is high peak average power ratio (PAPR) for a large number of subcarriers, resulting in many restrictions for practical applications. Coding is among the many PAPR reduction schemes have been proposed to overcome this problem. In this BER and PAPR of MIMO-OFDM system is calculated and the PAPR using the low density parity check codes is reduced.

Keywords- Orthogonal frequency division multiplexing (OFDM), MIMO, Peak-to-average power ratio (PAPR),Low density parity check (LDPC), and Complementary Cumulative Distribution Function (CCDF)
