MIMO receiver architecture for MIMO antenna systems using orthogonal coding

A new MIMO receiver architecture for MIMO antenna systems was conceived and evaluated. This uses orthogonal coding to multiplex together the received signals from several antennas so that they can be converted from RF to baseband using a single radio receiver. This technique avoids the necessary replication in transceiver that is nominally required for multiple antenna systems and hence there is a resultant cost saving.

In addition the technique does not suffer the loss of receiver performance that other methods such as time multiplexing are subject to. The orthogonal codes can be based on Walsh functions. This technique is described in FLOWS D9. It is also possible that the same technique could be used for combining signal from differing wireless systems so that they could be multiplex for down conversion though a generic RF front-end.
