Vs serial port program
4.0
This is VS the serial communication more code and data. There are various types of the implementing method. Serial communications (Serial Communications) the concept is very simple, serial bit (bit) of bytes sent and received. Even more so than byte (byte) parallel communication slow serial interface can send data at the same time using a cable with another one line to receive data. It is simple and long distance communication can be achieved. Define parallel IEEE488 passage when equipment specified line length must not exceed 20 m, and must not exceed 2 metres in length between any two devices and for serial, length up to 1200 m. Typically, the serial port is used for transmission of ASCII code characters. Completed communication uses 3 wires, ground wires, sending, receiving, respectively. Due to the asynchronous serial communication port can send data over a thread on another thread while receiving data. Other lines used to shake hands, but not a must. Serial communication is the mo

OFDM simulation program
4.0
OFDM simulation OFDM (Orthogonal Frequency Division Multiplexing) orthogonal frequency division multiplexing, OFDM is actually MCM Multi-CarrierModulation, multi-carrier modulation. The main idea is: the channel is divided into several orthogonal subchannel, speed of high speed parallel data signals into data streams, on each sub-channel modulation for transmission. Orthogonal signal can be separated by adopting the technology at the receiving end, this can reduce interference between subchannels of ICI. Realization of Multicarrier transmission
