摘要

Multi-hop networks help in combating fading by employing a distributed space diversity system. The performance of the system can be further enhanced by employing a good error control code such as convolutional codes, which provide low implementation complexity and short delays. In this paper we investigate the error performance of a convolutionally coded multi-hop ad-hoc network in an OFDM wireless environment with serial and selection relaying. In particular, we investigate the effect of relaying scheme, channel, bandwidth, and path loss exponent on the performance. Results show that the relaying improves the system greatly especially in the case of selection relaying and in high pat loss environments.
