Title
A novel adaptive antenna architecture - subcarrier clustering for high-speed OFDM systems in presence of rich co-channel interference
Abstract
For future high-speed orthogonal frequency division multiplexing (OFDM) wireless communications, two major system requirements will exist: broadband transmission and rich interference elimination. Because of its broadband nature and limited frequency allocations worldwide, interference from co-located wireless LAN operating in the same frequency band will become a serious deployment issue, since interference may have a large amount of multipath and also have similar levels of received power compared to the desired signal. This paper presents recent investigations in OFDM smart antenna systems, more specifically the signal properties in the frequency domain, for co-channel interference detection and rejection. A novel architecture is proposed in this paper, which is a complexity-reduced frequency-domain technique using subcarrier clustering. Research results are presented and show that the proposed architecture can achieve high performance with low complexity, within a rich multipath environment with low signal to noise plus interference ratio (SNIR).
