Introduction 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-erro ...

We simulate uncoded BER of BPSK modulated data as a function of SNR -in an AWGN channel -in a Rayleigh fading channel -in an AWGN channel when direct sequence spreading is used and compare results to the theoretical ones. We assume coherent receiver and perfect synchronization.

A combined space鈥搕ime block coding (STBC) and eigen-space tracking (EST) scheme in multiple-input-multiple-output systems is proposed. It is proved that the STBC-EST is capable of shifting hardware complexity from the receiver to the transmitter without any bit error rate (BER) performance loss. A ...

The use of hardware description languages (HDLs) is becoming increasingly common for designing and verifying FPGA designs. Behavior level description not only increases design productivity, but also provides unique advantages for design verification. The most dominant HDLs today are Verilog and VHDL ...

GNSS_SDR是一套不可多得的matlab代码。它给出了接收机每一部分的子函数，编程效率高，可读性强。此外，A soft-defined GPS and Galileo Receiver系统的介绍了整个接收机的原理，并针对程序给出说明，通俗易懂。

This file is distributed in the hope that it will be useful, but WITHOUT WARRANTY OF ANY KIND. Author(s): Ole Saether DESCRIPTION: This example should be used together with ex2a-tx433.asm. One nRF9E5 evaluation board (receiver) should be programmed with the hex-file generated ...

TIME HOPPING SPREAD SPECTRUM SIGNALS (ULTRA WIDE BAND SIGNALS) - UWB SIGNAL DESCRIPTION - THE UWB TRANSMITTER - THE UWB RECEIVER

m序列的生成器，rake接受，简单易用，希望对大家有帮助。。。

These files in Matlab implement a conventional DS -CDMA detector using QPSK modulation and matched filters in the receiver.

The Open Radar Data Acquisition (ORDA) subsystem replaces the current WSR-88D Radar Data Acquisition subsystem with improved receiver and signal processing hardware and with improved user interface, signal processing and diagnostics software. This paper will discuss the input data from the digital r ...
