Patent ID: 8625700

Claim:
An evaluation device for providing a transceiver system with transceiving performance information thereof, the transceiver system including a transmitter that has a plurality of transmit antennas and a receiver that has a plurality of receive antennas for receiving signals from the transmitter, and modeling channels between the transmitter and the receiver using Nakagami distribution with a fading parameter, said evaluation device comprising: a setting module operable to set an average signal-to-noise ratio (SNR) for the channels between the transmitter and the receiver of the transceiver system; a computing module operable, based upon the fading parameter, the average SNR, a number of the transmit antennas and a number of the receive antennas, to estimate at least one of an average output SNR, a bit error rate and an outage probability that are related to signals received by the receiver of the transceiver system; and an output module operable to provide the transceiver system with the average SNR and said at least one of the average output SNR, the bit error rate and the outage probability as the transceiving performance information of the transceiver system; wherein said computing module is operable to estimate one of the average output SNR, the bit error rate and the outage probability by computing a finite number of summation operations, and the number of the summation operations is independent from the number of the receive antennas and the fading parameter.
