Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The stack-based iterative precoding (SBIP) is an efficient algorithm that achieves a tradeoff beten bit error rate (BER) performance and computational complexity in multi-user MIMO downlink systems. ,  propose an adaptive SBIP algorithm with variable candidate set and statistically derived threshold for pruning. By analyzing the upper bound of accumulated metric, the range of candidate set is calculated. The probability distribution is also derived for statistical pruning of the tree search. Applying these ideas, the number of undesirable node visit is significantly reduced. Monte-Carlo simulations show that the proposed algorithm considerably reduces the computational complexity whereas the performance is close to that of sphere encoder (SE).
