A Nyquist Filter based Technique to Reduce PAPR in OFDM- MIMO Communication System
نویسندگان
چکیده
This paper describes the nyquist filter based technique to reduce the peak to average power ratio (PAPR) in multiple input multiple output Orthogonal Frequency Division Multiplication (MIMO-OFDM) systems. OFDM-MIMO system faces one of the main problems regarding PAPR of a transmitted signal. In present paper a nyquist filter along with conventional selected mapping (SLM) and alternative multiseqence (AMS) techniques are used for reducing the PAPR. The nyquist filter reduces the peak power of the transmitted signal and this may cause the reduction in PAPR. The simulated results are compared with conventional SLM and AMS techniques. Proposed nyquist filter based technique shows the lesser PAPR than the conventional SLM and AMS techniques. Coding and simulation has been done in Matlab 7.6.

Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...
