Abstract
Embodiments include systems and methods for improving performance of multiple spatial communications channels. Embodiments comprise power loading a steering matrix to achieve improved performance.
Claims21
A method for spatial channel steering in a wireless network, comprising:
- obtaining a steering matrix, wherein obtaining the steering matrix comprises updating the steering matrix at a rate that is substantially greater than a rate at which the power loading matrix is updated;
- modifying the steering matrix by a power loading matrix to produce a power loaded transmit steering matrix;
- wherein the power loading matrix is determined adaptively based on a measurement of system performance;
- and
- applying the power loaded transmit steering matrix to information signals to be transmitted.
2 more elements
A wireless system, comprising:
- a receiver to receive a steering matrix V transmitted by a wireless device;
- and
- a transmitter to post-multiply V by a power loading matrix, A, and to apply the resultant matrix to information signals to be transmitted;
- wherein A is determined according to a measurement of performance;
- wherein the transmitter updates the steering matrix at a rate that is substantially greater than a rate at which the power loading matrix is updated.
2 more elements
A wireless-capable unit, comprising:
- Direct Random Access Memory (DRAM) connected to a receiver;
- a receiver to receive by an antenna a steering matrix V from another wireless-capable unit;
- a packet error monitor to detect packet errors and to determine a packet error rate;
- a power loading matrix calculator to determine a power loading matrix A, adaptively, in response to the packet error rate;
- and
- processing circuitry to post-multiply V by A and to apply the resultant matrix to a vector of information signals, y;
- wherein the processing circuitry updates the steering matrix at a rate that is substantially greater than a rate at which the power loading matrix is updated.
4 more elements
A machine-accessible medium containing instructions for beam steering, which, when the instructions are executed by a machine, cause said machine to perform operations, comprising:
- receiving a steering matrix V transmitted by a wireless device;
- post-multiplying V by a power loading matrix, A, and applying the resultant matrix to information signals to be transmitted;
- wherein A is determined according to a measurement of performance;
- and
- updating the steering matrix at a rate that is substantially greater than a rate at which the power loading matrix is updated.
