This paper proposes an efficient wireless uplink strategy named filter bank single carrier frequency division multiple access. The proposed system combines the low peak-to-average power ratio of precoded orthogonal frequency division multiple access with the reduced out-of-band emission of filter bank multicarrier scheme. We present a complete mathematical analysis of the proposed model and derive the conditions to be fulfilled by the transmit filter for perfect data recovery. We further introduce a transmit filter design to enhance the peak-to-average power ratio and out-of-band emission characteristics of the proposed system. This paper also analyzes the sensitivity of the filter bank single carrier frequency division multiple access system to carrier frequency offset (CFO) and suggests a low complexity interference compensation scheme, under the assumption of perfect knowledge of CFO at the receiver. Later on, the assumption on CFO parameter is removed, and a blind interference compensation technique based on firefly algorithm is developed. Finally, a detailed simulation study is performed to substantiate the effectiveness of the proposed methods.KEYWORDS carrier frequency offset, filter bank multicarrier, firefly algorithm, out-of-band emission, peak-toaverage power ratio, precoded OFDMA

“…An OFDM system has many advantages that make it superior to the rest of the multicarrier modulation techniques, such as a high capacity, immunity against intersymbol interference, and efficient bandwidth utilization [1][2][3]. OFDM is also utilized in the long-term evaluation (LTE) standard for fourth generation (4G) mobile communications [7,8], and OFDM has recently been considered as one of the essential candidates in fifth generation (5G) wireless communication systems [9].

New low-complexity segmentation scheme for the partial transmit sequence technique for reducing the high PAPR value in OFDM systems

et al. 2018

Orthogonal frequency division multiplexing (OFDM) has been the overwhelmingly prevalent choice for high‐data‐rate systems due to its superior advantages compared with other modulation techniques. In contrast, a high peak‐to‐average‐power ratio (PAPR) is considered the fundamental obstacle in OFDM systems since it drives the system to suffer from in‐band distortion and out‐of‐band radiation. The partial transmit sequence (PTS) technique is viewed as one of several strategies that have been suggested to diminish the high PAPR trend. The PTS relies upon dividing an input data sequence into a number of subblocks. Hence, three common types of the subblock segmentation methods have been adopted—interleaving (IL‐PTS), adjacent (Ad‐PTS), and pseudorandom (PR‐PTS). In this study, a new type of subblock division scheme is proposed to improve the PAPR reduction capacity with a low computational complexity. The results indicate that the proposed scheme can enhance the PAPR reduction performance better than the IL‐PTS and Ad‐PTS schemes. Additionally, the computational complexity of the proposed scheme is lower than that of the PR‐PTS and Ad‐PTS schemes.

Although the OFDM system has been gaining importance in recent years, the high peak to average power ratio is considered the main limitation of the system. The oversampling operation in the frequency-domain plays an essential role in the PAPR calculations precisely. The main purpose of the paper to draw attention to zero-padding methods which are used to oversampled baseband OFDM signals. Moreover, to study the influence of the zero-padding methods on the accuracy of the PAPR calculations, and the spectral spreading of the OFDM signals. Simulation results show that the zero-padding method which inserts the zeros at the center of the baseband OFDM signal is better than the other zero-padding methods in terms of both accuracy PAPR calculations and spectral distribution.
