摘要
It is well known that Low Noise Amplifier (LNA) is the first part in RF receiver. The task of LNA is to provide a reliable power gain, while maintain the desired Signal to Noise Ratio (SNR). In wireless system, especially for Multiple-input-multiple-output (MIMO) system, the channel capacity sensitively grows as a function of SNR. Therefore, the changes in SNR due to LNA definitely alter the system capacity. In this paper, the effect of LNA on MIMO channel capacity is presented. By using the characteristic of LNA collected from the commercial products, the simulated capacity can be reasonably investigated. The results indicate the serious consideration on selecting LNA as it may degrade the MIMO capacity up to 26.4%.
