Sigma调制功能，便可提高其频率精度，大幅降低相位噪音及带内杂散信号，并???持极高的切换速度。系统设计工程师可以利用 Delta Sigma PLL将比较频率提高到很高的水平，以大大降低相位噪音。但高比较频率会导致产生周期滑动(cycle slipping)现象。-Sigma modulation function, can increase its frequency accuracy, dramatically reducing the in-band phase noise and spurious signals, and??? Holders of high switching speed. System design engineers can take advantage of Delta Sigma PLL compares the frequency increased to a very high level in order to significantly reduce the phase noise. However, the high comparison frequency would result in sliding cycle (cycle slipping) phenomenon.

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
