Patent ID: 8831113

Claim:
A method for transmitting information through a powerline medium, the method comprising: determining a power adjustment factor based at least in part on channel-descriptive information associated with a channel estimate, the channel estimate representing an estimate of a channel between two or more inputs of the powerline medium and one or more outputs of the powerline medium; obtaining two or more transmit values based on a symbol vector that includes a first symbol from a first symbol stream and a second symbol from a second symbol stream, the first and second symbol streams associated with an information bit stream, wherein obtaining the two or more transmit values includes computing a transmit vector by multiplying the symbol vector by the power adjustment factor and by a precoding matrix derived from the channel estimate, such that the two or more transmit values are specified by respective components of the transmit vector; and transmitting the two or more transmit values, respectively, through the two or more inputs of the powerline medium.
