Abstract
A new frequency hopping scheme is herein proposed for blind space-time suppression of co-channel interference in FH-CDMA peer-to-peer wireless communications1. The proposed blind adaptive "smart antennas" signal processing scheme maximizes the signal-to-interference-and-noise ratio (SINR) without prior knowledge of (1) the (possibly overlapping) hop sequences of multi-user interferers, (2) the fading channel's (possibly spatially and temporally decorrelated) space-time impulse response2, and (3) the mobile receiver antennas' nominal or actual gain/phase responses. The proposed scheme can reject "spectral splatter". This scheme may be implemented with only one receiving antenna, or as a space-time version for any number of antennas (as few as two), thereby exploiting any spatially decorrelated fading across the receiving antennas. All the above are made possible in the present scheme by substituting by a dedicated "dump" frequency for the desired signal's signature hop-sequence bins on a regular and rotating basis a priori known to the mobile receiver, thereby allowing adaptive estimation of the interference and noise affecting the desired signal.
