On The Designed And Constructed Feedback Shift-Register Encoder
Abstract
Information transmission in noisy channels can be achieved with vanishingly small probability of error by proper coding of the information as long as the encoding rate is less than the channel capacity. An encoder capable of cyclical shifting of data, and which can therefore be used for Bose-Chaudhuri and Hocquenghem (BCH) coding, has been designed and constructed using discrete components. It comprises basically four bistable multivibrators and an exclusive-OR device. On completion, the encoder performed cyclic code generation satisfactorily.
Keywords: Error coding, code rate, channel capacity, generator polynomial.
