1. An incremental lattice reduction method for a multiple-input multiple-output communication system, comprising: receiving an input signal at a plurality of input terminals; performing a first detection sub-method on at least a portion of the input signal to obtain a primary symbol vector estimate; evaluating a reliability assessment condition using the primary symbol vector estimate; terminating the incremental lattice reduction method if the reliability assessment condition is satisfied; and if the reliability assessment condition is not satisfied, performing at least one iteration of a second lattice reduction detection sub-method to obtain a secondary symbol vector estimate.
