Transmitter beamforming steering matrix processing and storage

A transceiver comprising:

• a steering matrix decompression unit operable to decompress a plurality of stored beamforming steering matrices, wherein the beamforming steering matrices are associated with a plurality of subcarriers of an RF signal received at the transceiver;
• a phase estimation unit operable to determine a phase difference between corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices of the plurality of beamforming steering matrices;
• a phase rotation unit operable to perform phase rotation on the corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices based on the determined phase difference associated with the corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices to improve phase continuity between consecutive beamforming steering matrices;
• an interpolation unit operable to interpolate the beamforming steering matrices to ungroup the beamforming steering matrices;
• and
• a beamforming processing unit operable to apply the beamforming steering matrices to data to be transmitted by the transceiver to generate beamformed data streams.

One or more machine-readable storage media having stored therein a program product, which when executed by one or more processor units causes the one or more processor units to perform operations that comprise:

• decompressing, at a transceiver system, a plurality of stored beamforming steering matrices, wherein the beamforming steering matrices are associated with a plurality of subcarriers of an RF signal received at the transceiver system;
• determining, at the transceiver system, a phase difference between corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices of the plurality of beamforming steering matrices;
• performing, at the transceiver system, phase rotation on the corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices based on the determined phase difference associated with the corresponding beamforming steering vectors of each pair of consecutive beamforming steering matrices to improve phase continuity between consecutive beamforming steering matrices;
• interpolating, at the transceiver system, the beamforming steering matrices to ungroup the beamforming steering matrices;
• and
• applying, at the transceiver system, the beamforming steering matrices to data to be transmitted by the transceiver system to generate beamformed data streams.
