Abstract :
Peak-to-average power ratio (PAPR) reduction in a distributed extended orthogonal space frequency block coding transmission scheme with two-bit group feedback for broadband cooperative four relays system is addressed. The PAPR reduction technique is based on amplitude clipping at the source, and the relays apply extended orthogonal space frequency block coding (EO-SFBC). The decoding method is based on the iterative amplitude reconstruction (IAR) technique. The simulations of the proposed system verify that the four relay cooperative transmitter diversity scheme with two-bit group feedback and IAR decoding achieves almost the same improvement in bit error rate (BER) as the two-bit pertone feedback relay cooperative transmitter with the same decoding technique, whilst limiting the source PAPR, and reduction the feedback overhead by 93.75%.
