This is my original implementation of the V-BLAST algorithm for MIMO channels using QPSK modulation. I'm urgently seeking assistance with a channel estimation algorithm resource - specifically a MATLAB implementation of LS algorithm for Rayleigh fading channels, as I have a deadline approaching in two days. Any help would be greatly appreciated and would be truly lifesaving!
1) Develop MATLAB simulation programs for both BPSK and QPSK modulation-demodulation systems with specifications: l Transmit and receive filters implement root-raised-cosine roll-off filtering; l Channel noise modeled as additive white Gaussian noise (AWGN). 2) Plot bit error rate (BER) versus signal-to-noise ratio (SNR) curves for BPSK and QPSK modulation schemes and compare with theoretical performance curves.
Implementation of Quadrature Phase Shift Keying (QPSK) modulation in Orthogonal Frequency Division Multiplexing (OFDM) systems using MATLAB programming
This MATLAB m-file implements MPSK (BPSK, QPSK, 8PSK) simulation with Gray coding, comparing theoretical and simulated performance metrics. The code demonstrates satellite link design examples using QPSK/8PSK when bit rate exceeds channel bandwidth, featuring constellation mapping, BER calculation, and channel modeling implementations.
