Abstract :
We analyze the performance of a CDMA ALOHA scheme by considering the packet collision probability as well as the bit error probability. We propose a new CDMA ALOHA/FEC scheme which uses a block FEC code in the data link layer for correcting bit errors of the received packets. By analyzing the proposed scheme, we show that the system throughput closely relates to the bit error rates. The results also show that the system throughput can be significantly improved by using the FEC coding, approaching to the value which is competitive with the error-free channel
