This LDPC software is intended as an introduction to LDPC codes computer based simulation. The pseudo-random irregular low density parity check matrix is based on Radford M. Neal’s programs collection, which can be found in [1]. While Neal’s collection is well documented, in my opinion, C source codes are still overwhelming, especially if you are not knowledgeable in C language. My software is written for MATLAB, which is more readable than C. You may also want to refer to another MATLAB based LDPC source codes in [2], which has different flavor of code-writing style (in fact Arun has error in his log-likelihood decoder).

Image Compression A collection of simple routines for image compression using different techniques. 图象压缩的不同方法 BTCODE: Image compression Using Block Truncation Coding. PYRAMID: Image compression based on Gaussian Pyramids. DCTCOMPR: Image compression based on Discrete Cosine Transform. IMCOMPR: Image compression based on Singular Value Decomposition. The given codes can be also used in 2D noise suppression. Notes: The function "conv2fft" performs a 2D FFT-based convolution. Type "help conv2fft" on Matlab command window for more informations.

The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published officially by Microsoft. Instead more high level API s were published that should be sufficient for developers. Again, unfortunately they are not sufficient. For example the API for receiving notification of incoming SMS messages is arranged for exclusively for one application per type of SMS. Apparently this will be improved upon in Pocket PC 2003. Another area is the availablity of a true AT command modem interface to interact with the GSM modem directly, which is also absent.

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge
