Fountain code for compression

The Library Reference describes the C functions, data types, and protocols that are included as part of the QNX Neutrino RTOS.

Abstract: This application note describes the program and data flash and how to erase/write the flash using the built-in utility ROM. This application note applies to the MAXQ flash-based microcontrollers that use a sector erasable flash

EZW implementation which will use wavelet transforms and do the compression decompression using EZW coding algorithm

EZW coding implementation. using wavelet transforms as a key tool. compression and decoding is done using EZW algorithm.

EZW coding implementation. using wavelet transforms as a key tool. compression and decoding is done using modified EZW algorithm.

SPIHT coding implementation. using wavelet transforms as a key tool. compression and decoding is done using SPIHT algorithm.

load data from pc to hand held terminal and vice versa

We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.
