This paper investigates the possibility of employing a single carrier system using iterative equalisation at the receiver as a direct competitor to multi-carrier COFDM. The throughput, range and terminal complexities of a COFDM solution are compared with those of a single carrier iterative equalised approach for identical indoor channel conditions. The paper demonstrates that iterative equalisation outperforms COFDM in an indoor environment. However, from a cost/performance viewpoint, COFDM is still seen as the more attractive solution.
Abstract-This paper considers the performance and design of a reduced complexity iterative equalizer, for a system including a rate one recursive channel precoder. Recursive channel precoders have been shown to yield significant performance gains, in wireless communication systems, if designed correctly. Extrinsic information transfer (EXIT) charts are used to predict system performance and as a configuration design tool, to determine powerful precoder and detector parameters. Bit error rate (BER) results for BPSK and 8-PSK modulation are presented, to verify the performance predictions of the EXIT chart analysis. Results show that even with large degrees of state reduction, the iterative receiver can achieve significant interleaver gain, associated with the inclusion of the recursive precoder.
There is increasing demand for broadband wireless personal area networking devices, mainly fuelled by mobile multimedia applications such as wireless home networks. This paper investigates the suitability of iterative equalisation as a means of achieving low bit and packet error rates in a future high data rate personal area network standard. Baseband simulation results demonstrate the powerful IS1 mitigation and error correcting performance of such receivers when operating in representative indoor wideband channels.
