Spatial cooperative diversity technique in performance enhancement of GNSS receivers

This paper aims to develop spatial cooperative diversity techniques to proceed with the switch, selection, combination and optimization between antennas. The mathematical formulations of spatial cooperative diversity techniques in term of equal-gain and maximum-ratio combining methods are also demonstrated. After successful testing of the algorithms through simulated data, it has been found that the proposed technique presents a significant improvement in terms of post-processing signal to noise ratio (post-SNR) and detection probability in contrast to single antenna-based Global Navigation Satellite System (GNSS) receiver.
