As a 3-D numeric array, it has size N-by-M-by-P.N is the number of subcarriers, M is the number of OFDM symbols, and P is the number of transmit antennas.. Alternatively, if channelest is provided as a 3-D array, out is a 2-D numeric matrix of size (N × M)-by-P.In this case, the first two dimensions have been . MIMO with MMSE equalizer. 3, pp. This example shows spatial multiplexing schemes wherein the data stream is subdivided into independent sub-streams, one for each transmit antenna employed. Also, according to the second equation of the algorithm, it is converging extremely fast. System Model The system is defined by the characteristics of its main features: The simulations are carried out, unless stated otherwise, for 4 users in the cell, each Massive multiple input multiple output (MIMO), well viewed as one of the important techniques for fifth generation (5G) wireless communication, has attracted a great deal of research interest in current years [1-3].The main idea of massive MIMO is to deploy a large-scale number of antennas and employ some simple precoding processing or detection technologies at the base station (BS), which . Others. In a previous post, we had discussed a 2×2 MIMO transmission using BPSK modulation in Rayleigh channel with a Zero Forcing equalizer. MMSE_Equ.dll 2. MU-MIMO Precoder matlab code. Using MATLAB, the different simulation results are shown in the different graphs, which provide the comparison of the BER for different modulation techniques using different equalizers like MMSE, ZF, ZF-SIC, MMSE-SIC and ML with Rayleigh frequency selective fading channel. - Matlab code for DL power control. MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB).
