In this paper, multi-node hybrid Cooperative cellular communication is considered with Amplify and Forward (AF) and Decode and Forward (DF) replaying protocols. Most of researchers have evaluated the performance of cooperative communication either with DF or AF relaying protocols. Considering single DF relay at midway between Source and Destination, for fixed target error probability we have evaluated the performance of multiple AF relays with shortest path relay selection criteria. The analysis is further extended to compare the energy consumption per bit for selected multiple AF and single DF relays.

“…In the same way diversity is also achieved when the relay simply amplifies and forwards the message with Amplify-and-Forward relaying (AF). It is observed in [7][8], the relay in mid way between source and destination provides optimal performance gain.…”

Abstract-In this paper, we analyze the bit error rate (BER) and the throughput of decode-and-forward (DF) relaying with imperfect channel estimation and in the presence of a jammer in the network. We consider a single DF relay scenario with orthogonal cooperative protocols and an active jammer during all the transmission phases attacking the relay and destination nodes in the network. In our analysis, we assume that the complex fading channel coefficients are estimated at the relay and destination levels with errors. We derive the error performance and the throughput of the network then we quantify the impact of channel estimation and the jamming power through the derivation of analytical performance expressions. Our simulation results confirm the accuracy of our analytical BER expression and quantify the performance degradation due to channel estimation and jamming signals. Also, simulation results show the performance of the throughput of the proposed system.

“…However, in this paper common MRC as given in (3) is used for DF with SD link for simplicity. In another approach one could also analyze the BER at D including the impact of decision errors at R as derived in [12] for M -QAM. As this leads to rather complicated BER expressions, we will also not consider this approach here.…”

Abstract-In this paper, power allocation schemes are proposed for the total transmit power of the source and the relay in a triplet relaying system based on Bit Error Rate (BER) analysis. Considering Amplify-and-Forward (AF), Decode-and-Forward (DF) for relaying systems and direct transmission (DT) without relay, we perform a fair comparison with respect to their power consumption in order to achieve the same target BER at the destination. For coded systems, the relationship between the input and the output BERs of the decoder for specific channel codes is modeled by polynomials to facilitate the BER analysis. Additionally, the Feasible Relay Region (FRR) is investigated, which determines geographically when AF or DF outperforms DT.
