What are the parameters of a convolutional code?
Overview of Convolutional Codes (2) ¾A convolutional code is specified by three parameters or where –kinputs and noutputs • In practice, usually k=1is chosen. – is the coding rate, determining the number of data bits per coded bit. –Kis the constraint lengthof the convolutinal code (where the encoder has K-1memory elements).
How are output bits calculated in a convolutional code?
Generator polynomials are G1 = (1,1,1), G2 = (0,1,1), and G3 = (1,0,1). Therefore, output bits are calculated (modulo 2) as follows: n3 = m1 + m−1. Convolutional codes can be systematic and non-systematic: Non-systematic convolutional codes are more popular due to better noise immunity.
How to make a convolution encoder work?
5. Convolution Encoder • One bit input converts to two bits code. • ko =1, no= 2, Block length = (m+1)no =6 • Constraint length = 2 , Code rate = ½ + ++ Shift RegisterInput Encoded output 6.
