Ber Qam

In this file there are two m-files.One is function and other is program. So during running the program save both file in same folder.First open the function rect ,then and run the ber_QAM file. You will get the required result.Here simulation is performed for 10,000 symbols in the presence... Platforms: Matlab

theoretical and simulated BER are in good agreement in AWGN channel the result can be extended to general M-QAM using slight modification . Platforms: PHP

This script calculates BER for a numebr of SNR values in gaussian environment for QAM 16 Modulation.It calculates 100 errors for each BER measuremnet for better results.I hope this will be helpful for students of signal processing and communications alike. Platforms: Matlab

Convert::BER is a Perl module for ASN.1 Basic Encoding Rules. SYNOPSIS use Convert::BER; $ber = new Convert::BER; $ber->encode( INTEGER => 1, SEQUENCE => [ BOOLEAN => 0, STRING => "Hello", ], REAL => 3.7, ); $ber->decode( INTEGER => $i, SEQUENCE => [ BOOLEAN => $b, STRING =>... Platforms: *nix

OFDM Signal generation and decoding using 64-QAM as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. Just run the Model and with different SNRs in the AWGN Channel Block observe the performance of the OFDM. Please leave your... Platforms: Matlab

These files just to simulate or demo M-QAM modem in case BER, channel model, signals in t and f domain.Overal proses from bit insertion at modulator to bit estimated in demodulator. We can see the change of signal in each block diagram. Platforms: Matlab

You can rum these files by my_speech.m file, taking an value like my_speech(64, 'qam') in the command window of MATLAB. Platforms: Matlab

Use any simple radio transmitter to send Audio/Video or any other form of data via the soundcard. Rates up to 400kb/s possible. With two transmitters, 2way communication is possible. Uses quadrature amplitude modulation scheme (QAM). Robustness is done with Read Solomon coding, interleaving, and... Platforms: Windows, Linux

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication. Platforms: Matlab

This program calculates BER curve against SNR for QPSK Modulation in Gaussian Environment.It calculates 100 errors for for each SNR value before calculating BER. This gives a good approximation of BER.I hope this will help students alot.Please feel free to contact me should anyone has any queries. Platforms: Matlab
