Abstract :
We propose a lattice-reduction (LR) aided stack algorithm to MIMO detection. The scheme employs a combination of sorted QR decomposition, LR, stack algorithm, and boundary control. With the aid of the LR, the stack algorithm works under a better-conditioned channel. The LR-aided stack algorithm achieves near-optimal performance but with a reduced computational complexity. Especially for correlated channel, a significant savings in complexity is achieved.
