SYSTEM AND METHOD FOR TESTING A RADIO FREQUENCY MULTIPLE-INPUT MULTIPLE-OUTPUT DATA PACKET TRANSCEIVER WHILE FORCING FEWER DATA STREAMS

摘要

In accordance with the presently claimed invention, a system and method are provided for testing multiple-input, multiple-output wireless radiofrequency (RF) packet data signal transceivers while operating in such ways as to communicate their signals using various combinations or permutations of packet data streams without requiring termination or re-establishment of communication links following transitions from one combination or permutation of packet data streams to another.

1. A method of testing of a radio frequency (RF) multiple-input, multiple-output (MIMO) packet data signal transceiver device under test (DUT), comprising:
establishing a MIMO communication link between a test transceiver and a DUT for communicating via a plurality of N DUT packet data signals provided by said DUT for said test transceiver and a plurality of test packet data signals provided by said test transceiver for said DUT, wherein N is an integer; and maintaining said MIMO communication link while
corrupting at least a portion of one or more of said plurality of N DUT packet data signals to provide a partially corrupted plurality of N DUT packet data signals containing said plurality of N data streams,receiving, with said test transceiver, said partially corrupted plurality of N DUT packet data signals containing said plurality of N data streams and, responsive thereto, failing to timely provide, with said test transceiver, a corresponding portion of said plurality of test packet data signals, andfollowing said failing to timely provide, with said test transceiver, said corresponding portion of said plurality of test packet data signals, receiving, with said test transceiver, said partially corrupted plurality of N DUT packet data signals containing a plurality of N−M data streams, wherein M is an integer and 0
