Abstract
In multihop OFDM relay systems the end-to-end
throughput can be increased by incorporating subchannel
mapping (SCM) at the relay nodes. This helps in achieving high
data rate requirements for live streaming applications. Average
Symbol Error Probability (SEP) is an important measurement
for investigating wireless communication systems. This paper
presents the statistical and symbol error performance analysis
of the 2-hop OFDM based multicast strategy with Amplify and
Forward protocol and subchannel mapping scheme. Closed
Form expressions for probability density function (PDF) and
well-approximated symbol error probability of the signal to
noise ratio (SNR) for the kth mapped subchannel pair link are provided
