Modified Local Search Particle Swarm Optimization Algorithm Based on Channel Estimation with VHDL

Abstract

The aim of this paper, a physical layer prototype is designed for 4G communications systems which is designed on the basis of Orthogonal Frequency Division Multiplexing (OFDM) modem. The new Channel Rating Scheme was named "Improved Particle Squadron Local Search Analyzer" (MLS-PSO). Then, the implementation of the technique XILINX Virtex-7 by Field Programmable Gate Array (FPGA) and compared to the other Virtex type device. The damaged signal may be improved using system modulation and de-modulation technique through the advancement of the proposed method. When those variations are considerable over the data frame duration, developing precise channel estimators that are able to track the variations of a channel is especially important for the reduction of the training signalling that is required for adaptation of parameters. The suggested model is designed with the use of VHDL and verified for being functional in Model-Sim and implemented targeting Virtex-5 enhancement kit. The projected frequency of operation of the design is 102.097MHz; the area is 15% of the entire available area and the entire power of 0.314 W, which leads to better results model according to the area, power and speed performance.
