Title: Transmitter and receiver for mimo system
Inventor: CHUNG SEONG-TAEK
IPC: H04L12/28
Filed: 2001-11-14
Abstract: PROBLEM TO BE SOLVED: To attain a substantial improvement in capacity over the case of no feedback by using considerably less bandwidth than is required to feedback the channel estimate or channel statistics in a MIMO(multiple-input multiple- output) system. SOLUTION: An indicator of a rate and/or an indicator of a gain for transmission of a data substream are supplied as feedback for each data substream of an overall data stream. The indicator of the rate and/or the indicator of the gain may be the rate and/or gain directly or an encoded representation of the rate and/or gain. The best performance is achieved if indicators of both the rate and the gain are fed back. The rate and the gain are computed as a function of a channel estimate which is developed at the receiver. The transmitter may employ only one-dimensional data coding for each of the data substreams.
