Description: In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.-In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model.

Description: This set of scripts allows the shadowing of a building to be simulated. It allows the
interference between two systems operating at the same frequency to be studied.
This simulation can do two main types of simulations:
1. Animated simulation where we have a fixed system, with one or more transmitters,
and a single mobile interfering user. The shadowing for the mobile user and the
interference it generates can be studied. The animations store each frame as a
JPG file, which can be imported in to a video editing package to be converted to
a movie.
2. Interference between two systems at the same frequency, each with multiple
transmitters Platform: |
