Abstract

Channel coding plays an important role in wireless communication system to mitigate the corruption of noise, fading and interference introduce by the transmission channel. This is achieved by adding a certain degree of redundancy into the bitstream to allow receiver to detect and perform self-correction operation to the error. The ITU (International Telecommunication Union) have layout the key performance requirements in IMT-2020 (International Mobile Telecommunication – 2020) standard envisioning the upcoming 5G (5th generation) wireless are capable in providing lighting speed, ultra-reliable communications for broadband and IoT (Internet-of-Thing). In June 2015, ITU-R (International Telecommunication Union – Radiocommunication Sector) released the three main 5G application scenarios, eMBB (enhanced mobile Broadband), uRLLC (Ultra Reliable & Low Latency Communication) and last but not least mMTC (Massive Machine Type Communication). The organization also set up eight criteria that defined the capability of 5G network including peak data rate, user experienced data rate, mobility, latency, connection density, network energy efficiency, area traffic capacity and most importantly spectrum capacity which leads to the deployment of Polar Codes – the new coding technology. The discovery of Polar Codes is a major breakthrough in coding theorem as it is the first provable capacity-achieving code for any Binary input Discrete Memory-less Channel which is a strong contender to the state-of-art coding technique Turbo and Low-Density Parity-Check (LDPC), which are widely implemented in 3G (3rd generation) /4G (4th generation) network applications. Polar codes was constructed using the principle of channel polarization proposed by Erdal Arikan in 2008. The leading global service provider in telecommunication field, Huawei has declared that SCMA (Sparse Code Multiple Access), F-OFDM (Filtered – Orthogonal Frequency Division Multiplexing) and Polar Codes are the three key technologies to endorse Huawei’s new 5G air interface concept. This thesis focus on designing algorithm to construct polar code using Bhattacharyya Parameter and Successive Cancellation Decoder for polar code. Further, the performance of polar code with different design SNR (Signal – to – Noise Ratio) and block length,
