基于NSFC-OFDM的非协作式虚拟MIMO
A Non-cooperative virtual MIMO based on NSFC-OFDM
摘要
Abstract
In this work,a non-collaborative virtual MIMO (multiple input multiple output) based on NSFC (non-coherent space frequency code) and OFDM (orthogonal frequency division multiplexing) is proposed to counter the poor security performance and strong dependence on channel estimation of virtual MIMO using user-pairing algorithm.Basing on the analysis of the pair-wise error probability for NSFC,we define the coding criterion to obtain full diversity and optimal coding gain.Then,we present a valid pre-encoding and decoding for virtual MIMO utilizing the unitary matrices,which are obtained by singular value decomposing on the channel cyclic matrix.A novel virtual MIMO,based on the optimized NSFC and OFDM pre-encoding and decoding is proposed.Although the instantaneous channel state information is unavailable at both sender and receiver,the single-antenna users even gain the multiple antennas transmission effect in a non-cooperative way.Theory analysis and simulation results show that the proposed scheme achieves similar performance on the capacity and bit error rate to ideal MIMO.关键词
