simulateQSNR
Determine the SNR for a quadrature delta-sigma modulator using simulations.
The modulator is described by a noise transfer function (ntf)
and the number of quantizer levels (nlev).
The ntf/stf may be given in ABCD form.
The band of interest is defined by the oversampling ratio (R)
and the center frequency (f0).

Digital-filters
A filter is a system which modifies some special frequencies reletive to the others. As a result it is applicable in some applications when it is necessary to have different gains & phase shifts at different frequencies to perform specific filtering tasks. For example in an audio file which is corrupted by noise it is convinient to use a filter to cancel those frequencies which are affected by noise and consequently having a better sound quality. During this MATLAB experiment we are trying to cancel the noise frequencies out of the original signal frequencies to get the original signal. Due to do this task, different types of filters such as FIR and IIR filters are used. In FIR filters, we use two type of common windows such as fixed window like Hanning and adjustable window like Kaiser. In IIR filters four different types of filter such as Butterworth, Chebyshev I, Chebyshev II, Elliptic are used.

spread-frequency
扩频通信系统仿真实验, ①传输的数据随机产生，要求采用频带传输（BPSK调制）；
②扩频码要求采用周期为31的m序列；
③仿真从基站发送数据到三个不同的用户，各不同用户分别进行数据接收；
④设计三种不同的功率延迟分布，从基站到达三个不同的用户分别经过多径衰落（路径数分别为2，3，4）；
⑤三个用户接收端分别解出各自的数据并与发送前的数据进行差错比较。(Spread spectrum communication system simulation)
