ABSTRACT

Lenstra-Lenstra-Lovász (LLL) is an effective receiving algorithm for multiple-input-multiple-output (MIMO) system. However, LLL algorithm possesses the polynomial complexity and its character of convergence performs poor. Reduce the algorithmic complexity and speed up the convergence is the key problem in optimizing LLL algorithm. In this paper, a variant named the Mingle LLL algorithm which combines both fix and round measurement in size reduction procedure is proposed. By leading in fix operation, the algorithmic procedure is changed and it will directly skip the size reduction procedure with extremely higher probability. As a direct consequence, according to the simulation results, the Mingle LLL algorithm owns a faster rate of convergence compared to original LLL algorithm. And its algorithmic complexity is at most one order lower than original LLL algorithm in real field.
