This project demonstrates the use of secure hash functions technique to implement a file encryption / decryption system. This implemented application can encrypt / decrypt multiple files on the fly using a password. The password supplied by the user is used as the source message from which the hash code (key) is generated using the SHA algorithm. Then this key is used to enctypted the data in the file(s). This key is stored in the encrypted file along with the encrypted data.

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.
