This paper proposes a method based on Space-Time Block Coding (STBC) with Multiple-Input Single-Output (MISO) and Multiple-Input Multiple-Output (MIMO) set-up for use in wireless channels. It is enhancement in the data rate at which a signal is sent over a communication channel. Enhanced MIMO channel capacity (upto 850 Mbps) by increasing no. clc; clear all; close all; ndata=2; % number of randam data. It uses a channel modulation as BPSK modulation. In MIMO-OFDM Wireless Communications with MATLAB ®, the authors provide a comprehensive introduction to the theory and practice of wireless channel modeling, OFDM, and MIMO, using MATLAB ® programs to simulate the various techniques on MIMO-OFDM systems. Here is the code for a uniformly linear array MIMO, I want to modify it for a planar array. 3 Channel Capacity of SIMO and MISO Channels. Capacity and Performance Analysis of Space-Time Block Codes in Rayleigh Fading Channels 1A. Many Research scholars are benefited by our matlab projects service. Dirty Paper Coding vs. it is a matlab code about multiple input multiple output with orthogonal frequency domain multiplexing. We prove analytically that such physical MIMO channels have a finite upper capacity limit, for any channel distribution and SNR.
