When an IPv4 device needs to communicate with an IPv6 device, various relay services and tunnelling tricks have to be employed, with IPv6 packets getting wrapped inside IPv4 packets and vice versa.It seems likely that the two separate internets will have to live side by side for the foreseeable future.
Relay systems [2] have been well studied in the recent years, assuming various relay strategies, such as amplify-and-forward (AF) and decode-and-forward (DF) techniques [3, 4], etc.
The relay-assisted wireless communication systems have been investigated in the context of various relay protocols, which include amplify-and-forward (AF), decode-and-forward (DF), compress-and-forward (CF) protocols, etc. [5 7].
In order to derive the formulas for the bit error rate (BER) of the THCLs employing binary phase-shift keying (BPSK) modulation and various relay processing schemes, we introduce the Nakagami and Gamma approximation for finding the distribution functions of various variables encountered.
The main focus of this paper is on the multi-way relay channel which is introduced in [29] where achievable rates are found with various relaying schemes including amplify-and-forward, decode-and-forward, compress-and-forward, and lattice forwarding.
Against this background, in [25], we studied and compared various relay processing schemes in association with the two-hop communication links (THCLs), where multiple relays assisted one source to communicate with a destination.
Finally, the error performance of the various relay processing schemes are demonstrated and compared based on the results obtained by both simulations and evaluation of the formulas analytically obtained.
Finally, the BER performance of the various relay processing schemes has been demonstrated and compared.

In this paper, we have studied the BER performance of THCL systems with various relay processing schemes, including the DRP, ICRP, and CRP.
