Pilots and Least Squares work

by ComputingNotes
BPSK (Binary Phase Shift Keying), a fundamental digital modulation scheme. A receiver uses a simple technique called Least Squares (LS) Channel Estimation to defeat fading and multipath interference. Wireless Channel In this simulation, the channel is designed to be intentionally difficult. It includes two major issues of digital signals: The Transmission Strategy: The Pilot Block ... Read More

Notes from – pskmod: Modulate signal using M-PSK method https://au.mathworks.com/help/comm/ref/pskmod.html The pskmod function performs M-ary Phase Shift Keying (M-PSK) modulation, converting input symbols (X) into a complex baseband signal (Y). Key Syntax data = randi([0 M-1], 1000, 1); txSig = pskmod(data, M, pi/M); Adding fading to simulation models a more complex and realistic wireless channel ... Read More

Channel Estimation

by ComputingNotes
The goal is to solve for H (the Channel) in the equation: Y=H⋅X+N (Received Signal = Channel × Transmitted Signal + Noise) [1]W. Shen, “Deep Learning-Enabled Channel Estimation for Reconfigurable Intelligent Surfaces-Aided Wireless Communications”. 1. Pilot Insertion (The “Known” Data) The receiver cannot estimate the channel using random user data because it doesn’t know what ... Read More
