这是一个学习WinSocket编程的程序，它由3部分组成，一是发送Sender的程序，另一个是接收Receiver的程序，还有一个是信道CHANNEL。发送方发送的数据需要经过信道才能够被接收方接收到。这个信道是一个模拟信道，可以自由设置它成为可靠或者不可靠，在不可靠时又有几种情况。这些都是为了能够更好地去理解数据链路层的编程，对学习很有帮助。

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the CHANNEL bandwidth Wc (Band-limited CHANNEL).

Adaptive Filter. This script shows the BER performance of several types of equalizers in a static CHANNEL with a null in the passband. The script constructs and implements a linear equalizer object and a decision feedback equalizer (DFE) object. It also initializes and invokes a maximum likelihood sequence estimation (MLSE) equalizer. The MLSE equalizer is first invoked with perfect CHANNEL knowledge, then with a straightforward but imperfect CHANNEL estimation technique.

This project aim was to build wireless software modem for data communication between two computers using an acoustic interface in the voice frequency range (20Hz– 20,000Hz). The transmitting antenna is a speaker (frequency response of: 90Hz – 20,000Hz) and the receiving antenna is a microphone (frequency response of: 100Hz – 16,000Hz). The test files used as information files were text files. This goal was attained both in an incoherent scheme and in a coherent scheme. Build under Matlab code, our modem uses OFDM (orthogonal frequency division multiplexing) modulation, synchronization by LMS sequence, CHANNEL estimation (no equalizer) via pilot tones. The symbols are either PSK or ASK for a constellation size of 2 or 4. To optimize the probability of error, these symbols were mapped using Gray mapping. Report
