摘要：

In this paper, we analyze the performance of a CDMA_ALOHA scheme by considering the packet collision probability as well as the bit error probability. And 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 tile 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.
