Abstract:
1. A method of testing a communication device by transmitting data packets as a first codeword and a second codeword from a vector signal generator (VSG) to a device under test (DUT), comprising: manipulating the first codeword and the second codeword by precoding the first codeword and the second codeword; generating a first output signal and a second output signal from the manipulated first codeword and second codeword, respectively, wherein the first output signal is different than the second output signal; receiving, by the first DUT, a first signal from the VSG , wherein the first received signal of the DUT is a summation of the first output signal and the second output signal; receiving, by the DUT, a second signal from the VSG, wherein the second received signal of the DUT is a summation of the first output signal and the second output signal; manipulating the first received signal of the DUT and the second received signal of the DUT by precoding the first received signal and the second received signal; and generating block error rate results from the manipulated first received signal of the DUT and the manipulated second received signal of the DUT.
