Efficient BER Improvement Mechanism for Wireless E1/E1 ATM Links
In the wireless scenarios where the links are non-engineered, the typical BERs are of the order 1 in 100 to 1 in 1000. It is essential to incorporate a Forward Error Correction (FEC) with a robust synchronization scheme that achieves a BER improvement. An efficient BER enhancement mechanism is proposed including block synchronization scheme for E1/E1 (ATM) links with 1 in 10 day probability of false alarm and 0.9999 probability of detection with minimal or no bandwidth overhead. A study of the various forward error control schemes was done and RS encoding/decoding was the selected FEC code for the implementation.
