Abstract

This paper proposes a novel algorithm, named "Recursive vector Viterbi algorithm" applied for the multibeam interference cancellers. The proposed algorithm make it possible to reduce the computational complexity of the cancellers, ultimately. The basic idea of the algorithm is to divide the state transition of the vector Viterbi algorithm into the several steps, each of which corresponds to each beam in the multibeam. In spite of the division, the performance of the canceller based on the proposed algorithm scarcely degrades by virtue of assistance of the adaptive beam control implemented in the multibeam interference cancellers. Indeed, It is verified by computer simulation that 3-beam interference canceller has only 0.2dB performance degradation in 2-path Rayleigh fading channel in spite of one third of computational complexity compared with the conventional one.
