Patent ID: 7986650

Claim:
A radio frequency (RF) transmitter comprises: a baseband processing module; an up conversion module; and an RF front-end, wherein, when the RF transmitter is in an RF beamforming mode: the baseband processing module is operably coupled to: convert outbound data into an outbound symbol stream; and convert an inbound symbol stream into inbound data; the up conversion module is operably coupled to convert the outbound symbol stream into an up-converted signal; the RF front-end is operably coupled to: adjust coordinates of the up-converted signal to produce multiple adjusted up-converted signals; amplify the multiple adjusted up-converted signals to produce multiple outbound RF signals; and transmit the multiple outbound RF signals that combine in-air to produce an outbound beamformed RF signal; and wherein, when the RF transmitter is in a multiple input multiple output (MIMO) mode: the baseband processing module is operably coupled to: convert the outbound data into a plurality of block encoded streams of outbound symbols; and convert a plurality of streams of inbound block encoded symbols into the inbound data; the up conversion module is operably coupled to convert the plurality of block encoded streams of outbound symbols into a plurality of up-converted signals; the RF front-end is operably coupled to: adjust coordinates of the plurality of up-converted analog signals to produce a plurality of adjusted up-converted signals; amplify the plurality of adjusted up-converted signals to produce a plurality of outbound RF signals; and transmit the plurality of outbound RF signals as an outbound MIMO RF signal.
