چکیده

A serially concatenated code with interleaver consists of the cascade of an outer encoder, an interleaver permuting the outer codeword bits, and an inner encoder whose input words are the permuted outer codewords. In this paper we derive design guidelines for the outer and inner codes that maximize the interleaver gain and the asymptotic slope of the error probability curves.

Woven codes with outer warp: variations, design, and distance properties

In this paper we consider convolutional and block encoding schemes which are variations of woven codes with outer warp. We propose methods to evaluate the distance characteristics of the considered codes on the basis of the active distances of the component codes. With this analytical bounding technique, we derived lower bounds on the minimum (or free) distance of woven convolutional codes, wov...

Serial Concatenation of Interleaved Codes: Performance Analysis, Design, and Iterative Decoding

A serially concatenated code with an interleaver consists of the cascade of an outer code, an interleaver permuting the outer codewords’ bits, and an inner code whose input words are the permuted outer codewords. The construction can be generalized to h cascaded codes separated by h − 1 interleavers. We obtain upper bounds to the average maximum-likelihood bit-error probability of serially conc...

Analysis, Design, and Iterative Decoding of Double Serially Concatenated Codes with Interleavers

A double serially concatenated code with two interleaves consists of the cascade of an outer encoder, an interleaver permuting the outer codeword bits, a middle encoder, another interleaver permuting the middle codeword bits and an inner encoder whose input words are the permuted middle codewords. The construction can be generalized to h cascaded encoders separated by h – 1 interleavers, where ...

Design of Serially Concatenated Codes based on Iterative Decoding Convergence

The design of serially concatenated codes has yet been dominated by optimizing asymptotic slopes of error probability curves. We propose mutual information transfer characteristics for soft in/soft out decoders to design serially concatenated codes based on the convergence behavior of iterative decoding. The exchange of extrinsic information is visualized as a decoding trajectory in the Extrins...
