.A rigorous proof of MIMO channel capacity’s increase with antenna number[J].Optoelectronics Letters,2008,4(4):280-282 A rigorous proof of MIMO channel capacity’s increase with antenna number Abstract:       It is well known that adding more antennas at the transmitter or at the receiver may offer larger channel capacity, in the multiple-input multiple-output(MIMO) communication systems. In this letter, a simple proof is presented for the fact that the channel capacity increases with an increase in the number of receiving antennas. The proof is based on the famous capacity formula of Foschini and Gans with matrix theory. Hits: 3499 Download times: 172 View Full Text    Download reader
