Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates the advanced receiver employing interference rejection combining (IRC) modeling schemes for the channel estimation error. In a system performance evaluation, the block error rate (BLER) of IRC receiver should be modeled accurately. To do this, the link performance modeling of the IRC receiver, i.e., the output signal-to-interference-plus-noise power ratio (SINR) after IRC reception including the covariance matrix and channel matrix estimation errors, is very important in evaluating the actual performance of the IRC receiver in the system level simulation. This is because these errors affect the suppression of the interference signals for the IRC receiver. In this paper, we propose a modeling scheme for the channel estimation error according to the ideal channel response of all cells and a channel estimation filter to address channel fading fluctuations. The results of simulations assuming LTE-Advanced downlink with two transmitter and receiver antenna branches show that the proposed scheme accurately approximates the performance of the realistic IRC receiver including a channel estimation error, which estimates the covariance matrix and channel matrix of the serving cell based on the demodulation reference signal.
