FPGA Implementation of MC-CDMA Wireless Communication System Based on SDR-A Review

Abstract

Software Defined Radio (SDR) has the flexibility to modify the characteristics of the receiving and transmitting radio device, without physically adjusting the hardware, due to development in the system. Because of the increasing need for wireless communication applications so as to enable consumers to communicate anywhere through information led to the emergence of many communication devices to include the large amount of applications that every one of the devices needs power and thereby increase the total power. This study confirms that the wireless communication system for secured transmit data, fast and inexpensive; can be done by implementing using Partial Reconfiguration (PR) modern technology in FPGA developing based on SDR. The Speed and performance can be improved. The area also can be decreased. The new Xilinx, Vertex Series FPGA, provides the provision of PR. The power consumption can be reduced by applying power reduction techniques in the blocks. The combination of MATLAB (Simulink and M-file) and Simulink HDL Coder offers flexible capabilities for analysis, design; simulation, implementation, and verification. With all these capabilities, in a single system to reduce the time spent tuning for reducing the algorithms and models during rapid prototyping and experimentation and less time on HDL coding. Contribution/ Originality: This study contributes in the existing literature review for implementing MC-CDMA wireless communication system using Partial Reconfiguration (PR) that is a new technology in FPGA. 1. INTRODUCTION The wireless communications revolution started with the mobile phone at the beginning of the 80's and all the improvements which have led to the multiplication of mobile and wireless communications networks and standards [1]. The 1st Generation (1G) of technology was characterized by analog means voice only; 1G quality was too low and also had connections to low speed, but they effectively offered the inherent easiness of mobile communications. The system used in 1G was Frequency Division Multiple Access (FDMA) [2]. The 2nd Generation (2G) of technology is digital in the United States, most of the devices and services were digital. The spread of digital mobile

A Closed Form Selected Mapping Algorithm for PAPR Reduction in OFDM Multicarrier Transmission

“…Multiple signaling and probabilistic techniques (MSP), such as selected mapping methods (SLM) [24][25][26], partial transmission sequence (PTS) [27,28], phase optimization [29], tone reservation and tone injection [30], and constellation shaping [31,32], which generate a permutation of the multi-carrier signal and choose the signal with the minimum PAPR for transmission, or modify different parameters in the OFDM signal, and optimize them to minimize the PAPR.…”

A Novel PM-OFDM-CDMA System for 5G Wireless Communication with High Capacity and Low Energy Consumption

“…The notion of code induces the notion of the system's ability to manage a maximum number of users. In addition, MC-CDMA can is easily implemented in an FPGA (Nahar et al, 2017). In addition, MC-CDMA is an appropriate technique for 5G applications (Razavi, Dianati & Imran, 2017).…”
