Alphanumeric messages are encoded in POCSAG format and send to the serial port of a computer. The modem connects to the serial port of a computer and sends the message on the air through a transmitter.
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).
This application creates an USB Mass Storage drive on a host computer. The drive is created from the internal Flash or external SDRAM memory of the evaluation kit.
This application creates an USB HID (Human-Interface Device) keyboard on a host computer. Pressing any of the buttons on the board outputs characters or special keys on the host side
