Design of Turbo Code Interleaver Using Union Bound

유니온 상한을 이용한 터보코드의 인터리버 설계

Given the frame size and constituent encoders, interleaver plays a central role in a turbo code performance. Interleaver should be designed to generate a heavy weight codeword in the second encoder if the first encoder generates a low weight codeword. In this paper we present a search procedure for high performace interleaver whose performance is measured by computing union bound using the weight spectrum of all the weight 2, 3
