802.11系统PCF机制详细介绍论文，非常清楚。-a good paper described the PCF of 802.11 system.

链路路径损耗包括距离相关的路径损耗，阴影衰落，快衰落和天线增益。仿真考虑了域频 和时域快速信道变化。在每个RB中，信道（TX和RX天线之间的链路）被假定为具有零均值的复杂性白高斯随机变量，这在RB的频率范围内（180千赫）和 1 毫秒的持续时间内是恒定的。相邻的RB和时间间隔之间的信道变动是独立的。

呼叫阻塞率的计算和仿真：在时间轴上考虑。无论阻塞与否，下一呼叫到达时刻为当前呼叫到达时刻加上服从参数为1/λ的指数分布的呼叫间隔时间。一个呼叫到达时只需要判断呼叫的到达时刻和各个信道服务完成时刻的先后：如果前者比后者中任意一个大，说明至少有一个信道服务完成时刻比此呼叫到达时刻早，即此信道空闲，此时呼叫成功，应该先把此信道下一个服务完成时刻置为当前呼叫到达时刻，再加上服从参数为μ的指数分布的服务时间；反之，如果前者比后者中全部都小，说明所有信道在此呼叫到达后才会结束服务，即当前忙，此呼叫被阻塞掉了-call blocking probability calculation and simulation : the time frame to consider. Whether or not blocked, the next call arrived at the present moment to call time arrived with a subordinate parameters/ index distribution of the call interval. A call arrived only judgment call and the arrival time each channel service has completed a moment : If the former than the latter an arbitrary, and at least one channel is completed service calls than this moment arrived moments earlier, that this channel is idle, call this success, should first get here Channel a moment of complete services for the current call home arrival time, coupled with the parameters obey the exponential distribution services; Conversely, if the former than the latter, all

这是一个用MODEM拔号的C语言源代码范例-This is a dial-up modem using the C language source code examples

利用api函数进行收了邮件。包括了邮件的收取、发送、删除等常用功能-Use api functions upon receipt of a message. Including the receipt of the message, send, delete and other commonly used functions

A simple example to verify the feasibility of applying compressed sensing for channel estimation. The pilot applies a PN pattern in the frequency domain. The density of pilot is less than the Nyquist sampling rate. Also it is assumed there are sparsity in the channel taps, which is the basis for applying compressed sensing.
