Alamouti STBC MIMO OFDM System using ZCT Precoded Based SLM Technique for PAPR Reduction
OFDM system is combined with multipleinput multiple-output (MIMO) in order to increase the system capacity and diversity gain. However, one of the major drawback of MIMO-OFDM have high peak-toaverage power ratio (PAPR) in order to the signals transmittted on different antennas. In this paper, we propose Zadoff-Chu matrix Transform (ZCT) precoding based Selected Mapping (SLM) technique to reduce...
متن کاملPerformance Improvement of Ofdm System Using Papr Reduction
Orthogonal frequency division multiplexing (OFDM) signals have a generic problem of high peak to average power ratio (PAPR) which is defined as the ratio of the peak power to the average power of the OFDM signal. The drawback of the high PAPR is that the dynamic range of the power amplifier and digital-to-analog converter during the transmission and reception of the signal is higher. As a resul...
متن کاملPerformance Improvement in OFDM System by PAPR Reduction Using Pulse Shaping Technique
Orthogonal Frequency Division Multiplexing (OFDM) is an efficient method of data transmission for high speed communication systems. However, the main drawback of OFDM system is the high Peak to Average Power Ratio (PAPR) of the transmitted signal. OFDM consist of large number of independent subcarriers, as a result of which the amplitude of such signal can have high peak values. Pulse shaping u...
