“…At DAF, the relaying node receives the original signal, decodes it, corrects it with the help of error correction codes, re-encodes it and resends it to the receiver [6]. DAF has obviously better performance than AAF [7], [8], but only when there is an error correction code. DAF strategy demands more energy and computational source then AAF [6].…”

In a wireless communication system, cooperative diversity can be used to combat fading effects. In cooperative di versity, the system uses idle antennas, which are located at different locations, as relays. Cooperative communication with OFDM is widely used in communication systems and it enhances communication performance of the system. There are different methods to enhance the performance of OFDM systems, carrier interferometry code is one of them. While, carrier interferometry code increase the performance of the system and also reduces PAPR level. Carrier interferometry codes can be implemented on an OFDM system by using FFT and wavelet. In this paper we investigate the effect of the relay position on the carrier interferometry cooperative OFDM system which uses wavelet transform. The effect of the relay position is investigated over different combiners and relaying strategies. The results show that, relay position effects the performance of the system and optimal location for the relay is right between source and destination.

Cooperative diversity has spatial diversity effects on wireless communication systems to combat fading effects by using idle antennas as relays which are already located in the system. OFDM based cooperative communication is widely used in wireless communication systems and promises high data rate. However, OFDM has high PAPR problem. The high PAPR causes the interference and performance loss. Carrier interferometry codes boost overall performance of OFDM communication systems and decrease the level of PAPR. FFT can be used to realize carrier interferometry with no performance degradation. In this paper PAPR performance of the carrier interferometry OFDM by wavelet transform is analysed in a cooperative relay network. The results show that, the system which is a novel design of CI-OFDM has obviously better performance than traditional systems in terms of both BER and PAPR with the assist of wavelet transform.
