“…The results obtained in [19] for QAM were compared with the results obtained using the proposed scheme; it was observed that the proposed scheme works better than the conventional PTS and SLM techniques in [19]. Simulation for QAM was carried out as in [19] other modulators were used and it was observed that QAM gives better results.…”

Orthogonal frequency division multiplexing (OFDM) is a multicarrier communication technique and it has capability to rise above the frequency-selective fading problem, which is common in wireless broadband communications. This has made it popular since last few years. The OFDM system suffers from a number of drawbacks such as the high peak-toaverage power ratio (PAPR). Many PAPR reduction techniques used either destroy the system performance, which is the clipping technique or increases the overall complexity of the system, such as the selective mapping (SLM). In this paper a unique approach has been proposed to obtain a new code from the existing codes in order to reduce the bit error rate (BER), to mitigate the gap between the performance and Shannon limit while the bounded peak average power ratio (PAPR) of OFDM symbol is guaranteed. A new code based on the BCH with a Barthannwin Wave Filter has been proposed to achieve the desired results. General Terms BCH with Barthannwin Wave Filter

“…For this evaluation we have used QAM modulation and studied effect of different modulation orders such as 4QAM, 16QAM, 64QAM and 256QAM. Modulation order of the system plays an important role on system performance and its PAPR value also get affected by this [15,16].…”

One of the main objectives of multicarrier modulation is to provide multiple accesses for wireless communication systems with higher data rates while having minimum out of band radiation, high spectral efficiency and less complexity. Orthogonal frequency division multiplexing (OFDM), Universal filter multicarrier (UFMC), Filter bank multicarrier (FBMC) and Generalized frequency division multiplexing (GFDM) modulation techniques have been developed to support fourth generation and beyond 4G wireless systems. Demand of high data rate in fourth generation wireless communication systems has been fulfilled by OFDM techniques but it suffers from the limitation of less spectral efficiency and high PAPR (Peak to average power ratio). Thus to support next generation wireless systems other waveform models are getting attention. Among the techniques available, UFMC seems to be attractive due to high spectral efficiency and less complexity. It has not explored much so in this paper, performance of UFMC have been evaluated with different design factors such as number of sub bands, FFT (Fast Fourier Transform)size, filter characteristics and modulation under the light of PAPR.
