Method and apparatus to provide multiple-mode spatial processing to a terminal unit

A wireless remote terminal receiver in a remote terminal unit, the wireless remote terminal receiver comprising:

• a plurality of antennas, including a first antenna and one or more additional antennas;
• a receive processing unit coupled to the antennas to process the signals received at the antennas, including a delay and add processing unit to process the signals received at the first antenna and at one or more of the additional antennas, the delay and add processing unit to form a sum signal being the sum of the signal received at the first antenna and delayed versions of respective signals received at the one or more additional antennas, the receive processor further including a processor accepting the sum signal, the processor having multipath combining capabilities and forming a received signal, the receive processing unit further including a receive electronics unit, the receive processing unit to apply a selected spatial processing mode to the signals, the selected spatial processing mode being of a plurality of spatial processing modes, including one or more modes of one or more spatial processing methods.
