Probing scheme for diversity antenna branch selection

Abstract

A probing scheme for diversity antenna branch selection makes use of a physical waveform frame structure that includes a diversity selection portion. The diversity selection portion may be located anywhere in the physical waveform frame structure and includes one or more antenna branch probing portions. Several antenna branch switching time intervals are interleaved with the antenna branch probing portions. Several repeated Orthogonal Frequency-Division Multiplexing (OFDM) symbols are used to form the antenna branch probing portions and the switching time intervals. Diversity reception in radio frequency (RF) communications is performed by receiving a frame having the diversity selection portion with a system having L antenna branches and n RF receivers, and then taking measurements from n of the L antenna branches during one of the antenna branch probing portions.
