The Radio Interface Layer is the name for an interface that was developed especially for the Pocket PC Phone Edition. It is meant to abstract the interface with a phone/modem device. To achieve this it is closely modelled after the GSM AT command interface. Unfortunately the API was not published of ...

There are two files in the zip folder. bpsk_spread.m and jakesmodel.m Steps for simulation: 1] Run jakesmodel.m first 2] Then run bpsk_spread.m . 3] Note that during the first run bpsk_spread.m has no rayleigh fading.This is because the corresponding code has been commented 4] The resulting performa ...

Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate perfor ...

M-file uses random data which BPSK modulates a carrier to configure a BPSK UWB transmitter. The receiver demodulates the BPSK UWB carrier and the data is recovered.

M-file uses random data which BPSK modulates a carrier to configure a BPSK UWB transmitter. The receiver demodulates the BPSK UWB carrier and the data is recovered.

This m file models a UWB system using BPSK with the fifth order derivative of the gaussian pulse with correlation receiver and intgrator.

pashload是应用在linux下的网络带宽测试源程序精确度比较高 ///////////////////////////////////// Pathload is a tool for estimating the available bandwidth of an end-to-end path from a host S (sender) to a host R (receiver). The available bandwidth is the maximum IP-layer throughput that a flow can ge ...

The source codes are from the "Simulation and software Radio for mobile communication" It contain the channel model and CDMA Transmitter and receiver.
