•MASTER'S PROJECT : Evaluation and real time implementation of different techniques for a wireless communication channel

• AIM: This primary aim in developing this project was to get more familiar with embedded systems and their application in wireless systems. Also, the project helps in understanding some basic wireless concepts, which are very useful in making a wireless system more robust and error free.
  
• IMPLEMENTATION: An evaluation module from Texas Instruments is being used for implementation purposes. The EVM TRF6903 consists of the TRF603 transceiver chip and the MSP430 micro-controller on a single board. A JTAG interface is used to program the micro-controller and the data to be transmitted is given via the RS-232port. Window based program called Kickstart is available to program the micro-controller chip. The programming platform is embedded C and some ALP.
  
• DETAILS: Implementation of wireless schemes such as convolutional encoding, Viterbi decoding and block interleaving was performed. A comparative study of each of these schemes with respect to BER was done in order to determine the reliability of the scheme and integrity of the data while changing the distance of transmission and reception. It was noticed that for higher distances the channel resulted into fading and for such cases interleaving helped in improving the data integrity by a huge factor. On the other hand convolutional encoding and viterbi decoding also improved error rate by forward error correction techniques.
  
• STATUS: The project was completed successfully in August 2007 .
