BPSK Transmitter
- The basic parts of the BFSK transmitter are the preamble and the data input circuit. The preamble sequence is positioned in front of each packet of 122 bits for a total of 128 bits packet. The main purpose of the preamble is to facilitate the recepti
convolutional_encode
- simulating a convolutional encoder allows the user to input a source code to be encoded and also input the values of the generator polynomials. It outputs the encoded data bits, where 1/n is the code rate
viterbiDecoderConvolutionalCode
- Viterbi decoder for nonsystematic convolutional code. The encoder could be designed arbitrary through the generate matrix and parameter k. The number of row of generate matrix is output bits, and collom is constraint length. Parameter k is the number
convolutionalencoder
- Its a convolutional encoder with code rate of 1/2 and constraint length of 3. i/p=1 bit o/p=2 bits with 4 memory elements
