Under the assumption that the channel state information was available only at the receiver,the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergodic flat fading channel were derived.An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.

以信息论的观点为基础，在假设信道状态信息仅收端已知的情况下，采用等功率发射方案，研究了瑞利衰落信道下MIMO系统各态历经信道容量，推导了三种特殊MIMO信道的各态历经信道容量表达式，以及在小信噪比下等收发天线MIMO系统的容量近似公式，并通过仿真进行了验证，仿真结果表明该近似公式比较精确。

The anger of a good man lasts an instant,that of a meddler two hours,that of a base man a day and a night,that of a great sinner until death.

Reflections of hands and eyes abound, and one shot shows the phantasmagoric world of the rich as they dance behind the windows that separate them from the souls in second class and steerage.

The flow motions, including vortical, upward, and downward movements, inside the cyclone separator are very complicated and the behaviors of the air stream are difficult to observe by means of experimental methods.

旋风分离机内的流场是非常地复杂，气流有旋转、向上、向下等各种不同方式的运动，以实验的方法，很困难充分了解其气流的运动情形。

He has the address of every whorehouse in Paris, and the rates. Even from the ten franc joints he gets his little commission. And he knows the shortest way to any place you want to go. He will ask you first if you want to go by taxi; if you say no, he will suggest the bus, and if that is too high then the streetcar or the metro.

他有巴黎每一家妓院的地址，还有价目表，甚至从十法郎一回的下等妓院中他也能得到一笔小小的佣金，他还知道到你想去的地方的最近路线，他先问你愿不愿坐出租车去，如果你不愿，他就提议坐公共汽车，如果觉得车费太贵就坐电车或地铁去。

People see this as a here-and-now thing, not like,'If I buy this collector's coin right now, I'll put it under my mattress and it'll be worth a fortune 10 years from now,'' he said.
