APPARATUS FOR TRANSMISSION THROUGH MULTIPLE ANTENNAS

摘要

A space-time coding apparatus receives two groups of inputs and outputs two groups of outputs. A configuration of each output group is based on spatial diversity and a configuration between the groups of outputs is based on spatial multiplexing. The space-time coding apparatus may include two spatial diversity coders whose outputs are each connected two spatial multiplexing coders. A plurality of antennas may be respectively connected to outputs of each spatial multiplexing coder. Coding coefficients are configured so that a first wireless receiving terminal corresponding to a first group of outputs receives only input signal components of a first group of inputs, and a second wireless receiving terminal corresponding to a second group of outputs receives only input signal components of a second group of inputs.
