利用哈夫曼编码进行通信可以大大提高通信信道利用率，缩短信息传输时间，降低传输成本。这要求在发送端通过一个编码系统将传输数据预先编码；在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双工传输信息的信道），每端都需要一个完整的编/译码系统。为这样的信息收发站设计的一个哈夫曼编/译码系统。 (2-use Huffman coding communication can greatly enhance communication channel utilization, reduced transmission time, and lower transmission costs. This requires the transmitter through a coding system will transmit data in advance coding; The receiving end of the data came decoding (recovery). For dual-channel (that is, information can duplex transmission channel), each side needs a complete encoding/decoding system. For this information hubs designed a Huffman encoding/decoding system.

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s classical formula scales as one more bit/cycle for every 3 dB of signaltonoise ratio (SNR) increase, remarkably withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99 of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2 bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4 amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t
