Transmission scheme for multiple-input communication

摘要

Method for transmitting and receiving signals over at least one channel between at least one transmitter and at least one receiver, the channel comprising at least one group of sub-channels, the group comprising at least one sub-channel, including the procedures of estimating at least one line characteristic of the channel and selecting a transmission scheme for each group of the at least one group of sub-channels according to the estimated line characteristic, wherein the transmission scheme is selected between a single spatial stream transmission scheme and a multiple spatial stream transmission scheme.

1. A method for transmitting and receiving signals over at least one channel between at least one transmitter and at least one receiver, said at least one channel comprising at least two different groups of sub-carriers, each one of said at least two different groups comprising at least one sub-carrier, comprising:
estimating at least one line characteristic of said at least one channel; selecting a transmission scheme for each group of said at least two different groups of sub-carriers according to said estimated at least one line characteristic; wherein said transmission scheme is selected between a single transmit port transmission scheme and a multiple transmit port transmission scheme; and applying a respective power allocation scheme to each one of said at least one sub-carrier for each transmit path used; wherein said respective power allocation scheme is selected from a list consisting of:
allocating equal power to each at least one transmit path used for a respective sub-carrier;allocating all power to a single transmit path used for a respective sub-carrier; andallocating power to each at least one transmit path used for a respective sub-carrier according to a predefined finite set of power settings for a plurality of transmit paths.
