“…However, in a dispersive multipath channel, only with highly sophisticated interference cancellation techniques are used, DS-CDMA with a spread factor N can accommodate N simultaneous users, which becomes the disadvantage of DS-CDMA as it is challenging to implement. MC-CDMA is more comfortable to apply, and it can handle N simultaneous users with good bit-error-rate (BER) [12], using standard receiver techniques [3]. As mention earlier, MC-CDMA is a hybrid of OFDM [13] and CDMA.…”

This paper presents a low power multi-carrier code division multiple access (MC-CDMA) receiver on field-programable gate array (FPGA). Most of the wireless application nowadays such as wireless sensor networks, portable computation and many more require a low power design. Time-division multiple access (TDMA) is used in most wireless receivers are not very efficient since they adopt scheduling technique. The first objective of this paper is to design and verify a low power MC-CDMA receiver and the second objective is to implement the MC-CDMA receiver on FPGA. MC-CDMA act as a processor with the ability to process transmit or receive data simultaneously over a single communication channel. The MC-CDMA design in this paper consists of pipelined FFT and combiner. The primary purpose of pipelined FFT plus combiner module in this research is to execute the instruction on communication (data send and receive) and self-organization. Besides these two modules, there is a memory for temporarily storing the data and an internal clock, among other things. To accomplish these, the designs have been carried out using Verilog coding in Modelsim software, and the design verifications are done through Matlab. The design implementation is via Quartus and on DE2-115 Altera FPGA board. The functionality analyses have been carried out on simulation, and the hardware implementation of the MC-CDMA receiver is tested. Both simulation and hardware execution are successful where the receiver received and displayed the output accordingly. MC-CDMA achieves 39.13mW total power consumption.

Enhanced fractional frequency reuse approach for interference mitigation in femtocell networks

et al. 2020

View full text Add to dashboard Cite

Small cell networks are expected to heavily be deployed in wireless communication networks due to it ability to enhance signals quality and spectrum utilisation. However, interference is posing a major threat to wireless communication especially cellular femtocell networks whereby its performance is degraded in dense deployment areas. For this reason, an enhanced fractional frequency reuse approach is proposed in this paper to mitigate the interference in femtocell networks. This is achieved by dividing the service area and frequency into three regions and three sets whereby each set is allocated different frequency set. The femtocell location is later obtained and assigned frequency in accordance to the region. The proposed approach helps in reducing the interference, boost the signal to interference plus noise (SINR), and enhance the throughput.
