This code deals with the ber simulation for Qpsk and Bpsk for various values of snr. At least 10^6 transmission of bits has been considered. 10 different itaeration for snr has been taken.... CommunicationMatlab
This SCRIPT simulates ber
of Bpsk in AWGN channel. It perfroms the
1. Bpsk modulation and
demodulation of data and plot respective signals.
2. Addition of AWGN noise
with Bpsk modulated signal.
3. Plot constellation

4. Plot ber vs... MatlabMatlab
OFDM is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. A large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels. Each s... MatlabMatlab

In digital modulation techniques a set of basis functions are chosen for a particular modulation scheme.Generally the basis functions are orthogonal to each other. Basis functions can be derived using 'Gram Schmidt orthogonalization' procedure.Once the basis function are chosen, any vector in the si... CommunicationMatlab
Vector sum excited linear prediction (vsELP) is a speech coding method used in several cellular standards. The vsELP algorithm is an analysis-by-synthesis coding technique and belongs to the class of speech coding algorithms known as CELP (Code Excited Linear Prediction)... WindowsC++

Though the total channel is a frequency selective
channel, the channel experienced by each subcarrier in an OFDM system is
a flat fading channel with each subcarrier experiencing independent
So, assuming that the number of taps in the channel is lower than the
