Hybrid forwarding for serial and parallel wireless relaying in m-nakagami fading channel
Chanchal Kumar De, Sumit Kundu · 2011
In this paper, an adaptive forwarding strategy for wireless networks using relays in multi hop and cooperative network is analyzed. Two schemes, amplify-and-forward (AF) and decode-and-forward (DF) are investigated depending on channel condition. Further it allows switching between the two schemes according to channel condition. The bit error probability performance (BEP) for the proposed hybrid strategy has been evaluated in presence of m-nakagami fading. We have evaluated the BER performance for variable number of relays in multi hop and cooperative network. The impact of decoding threshold and `m' parameter on bit error rate (BER) is indicated. Further BEP performance is assessed using LDPC code.
