Iterative Decoding Algorithms for RS-Convolutional Concatenated Codes
نویسندگان
چکیده
This paper presents an iterative decoding algorithm for concatenated codes consisting of a ReedSolomon and a convolutional code, focusing on the code of the DVB-S standard. Existing solutions for the different decoding stages and their interfaces are discussed and their performance is compared. Besides, a new procedure is proposed to define the feedback signal from the output of the Reed-Solomon decoder to the input of the convolutional decoder that provides a significant improvement over existing solutions.

Reed - Solomon Hybrid Codes For Optical Communications
The astonishing performance of concatenated codes attracted many researchers and this has resulted in an explosive amount of literature since their introduction few years ago. As concatenation between codes did not actually arise from applying a pre-existing theory, most of their outstanding features remain to be explained. This paper gives some explanation of the concatenation between Reed Sol...
متن کاملConcatenated error-correcting entropy codes and channel codes
We propose a general class of concatenated errorcorrecting entropy codes and channel codes. In this way we extend and generalize the existing body of work on iterative decoding of entropy and channel codes. Using the structure and properties of serial concatenated codes, we employ error-correcting entropy codes as the outer code, and a convolutional code as the inner code. The generalization fr...
متن کاملPerformance of Hybrid Concatenated Trellis Codes CPFSK with Iterative Decoding over Fading Channels
Concatenation is a method of building long codes out of shorter ones, it attempts to meet the problem of decoding complexity by breaking the required computation into manageable segments. Concatenated Continuous Phase Frequency Shift Keying (CPFSK) facilitates powerful error correction. CPFSK also has the advantage of being bandwidth efficient and compatible with non-linear amplifiers. Bandwidt...
متن کاملHybrid Concatenated Codes and Iterative Decoding
A hybrid concatenated code with two interleavers is the parallel concatenation of an encoder, which accepts the permuted version of the information sequence as its input, with a serially concatenated code, which accepts the unpermuted information sequence. The serially concatenated code consists of an outer encoder, an interleaver, and an inner encoder. An upper bound to the average maximum-lik...

I n this paper we propose new decoding algorithms to be embedded in the iterative decoding strategy of parallel concatenated convolutional codes. They are derived f rom the optimum maximum-a-posteriori algorithm and permit a continuous decoding of the coded sequence without requiring trellis termination of the constituent codes. Two basic versions of the continuous algorithm and their suboptimu...
