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 signals. OFDM consist of large number of independent subcarriers, as a result of which the amplitude of such a signal(More)

A new method is developed to optimize the prototype filter response. The design problem is formulated as nonlinear unconstrained optimization of(More)
In this paper various Hybrid techniques of keying and coding algorithm have been implemented to efficiently reduce the peak-to-average-power ratio (PAPR) problem that exists in MIMO-OFDM. A novel Selective Level Method (SLM) method is used as a basic technique which has been combined with other keying and transform techniques. Square root technique and(More)
