在多输入多输出系统中的鲁棒球形译码的实现-We present a maximum-likelihood decoding algorithm for an

arbitrary lattice code when used over an independent fading channel with

perfect channel state information at the receiver. The decoder is based on

a bounded distance search among the lattice points falling inside a sphere

centered at the receved point. By judicious choice of the decoding radius

we show that this decoder can be practically used to decode lattice codes

of dimension up to 32 in a fading environement.
