Analysis on the Inter-carrier Interference of MIMO OFDM with Distributed Antenna Systems ⋆
نویسندگان
چکیده
The effect of Doppler spreading destroys the orthogonality of the subcarrier in OFDM giving rise to inter-carrier interference (ICI), and the Doppler spectrum types of MIMO with distributed antenna systems (DAS) may not be the same. This paper focuses on the analysis of ICI for MIMO OFDM with DAS. Firstly the instantaneous expression of SINR is presented using zero force (ZF) detector. Then the carrier to interference (C/I) ratio is derived to demonstrate the effect of the ICI under general Doppler spectrum. Numerical results show the correctness of the C/I ratio derived.

OFDM is a multicarrier modulation technique in which a high rate bit stream is split into N parallel bit-streams of lower rate and each of these are modulated using one of N orthogonal sub-carriers. In a basic communication system, the data is modulated onto a single carrier frequency. OFDM is a promising candidate for achieving high data rates in mobile environment because of its multicarrier ...
