UFMC system performance improvement using RS codes for 5G communication system

Abstract

Fifth generation (5G) mobile communication is expected to be deployed in several countries by 2020. Where, the data consumptions are expected to be increased to 30% thus, it cannot be supported by the present technologies 3G and 4G. In contrast, looking for new alternative modulation techniques of orthogonal frequency division modulation (OFDM) system which is suffering from high peak to average power ratio (PAPR) and out of band (OOB) side lobes are needed to use in 5G communication system. Hence, universal filtered multi-carrier (UFMC) is considered as alternative waveform to overcome of OFDM disadvantages. In communication systems, channel coding is considered vital part, where error correction codes (ECC) are used to detect and correct the errors which is occurring in channel noise. In this paper, RS codes are suggested with UFMC system to achieve the reliability of information transmission over noisy channels. The results showed that although, the values of PAPR levels for using RS codes in UFMC increased to 8.8653dB against 6.9735 dB for OFDM system. However, there are significant improvements in BER performance owing to use RS codes against uncoded-UFMC system. Furthermore, the values of OOB in UFMC system was lower than OFDM system.

An improvement and a fast DSP implementation of the bit flipping algorithms for low density parity check decoder

“…More for used mobile radio systems, the information is frequently disturbed by noise in the transmission channel. Thus, a high-performance error-correcting code is essential and obviously vital for digital transmissions making a development of high-performance decoders with low latency, high working frequency and high throughput a challenged research problem [1], [2].…”

UFMC and f-OFDM: Contender Waveforms of 5G Wireless Communication System

“…In contrast, Universal Filtered Multi carrier (UFMC) system is also considered one of the contender candidate waveform for 5G communication systems owing to its immunity against Inter Carrier Interference (ICI) and ISI as well as it appropriates for low latency scenarios [14]- [18]. Furthermore, UFMC is considered an alternative waveform can be overcoming of OFDM disadvantages and maintaining its advantages [16], [17]. It was compared with OFDM which is used in 4G networks and analysis the effectiveness of each of them [15].…”
