The software is capable to simulate space time code [1] for QPSK modulation using different number of state. Examples of generator matrix up to 256 stetes are provided. Variable signal to noise ratio (snr) might be applied to produce bit error rate (BER) or frame error rate (FER) curves.

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.

This document contains a detailed description of the usage and configuration of the JSVM [Joint Scalable Video Model] software for the Scalable Video Coding [SVC] project of the Joint Video Team [JVT] of the ISO/IEC Moving Pictures Experts Group [MPEG] and the ITU-T Video Coding Experts Group [VCEG]. It provides information how to build the software on Windows32 and Linux platforms. It contains a description of the usage and configuration for the binaries built from the software package, including examples for spatial, snr and combined scalability scenarios. Guidelines for the integration and validation of new tools in the software are provided.
