Recursive convolutional codes for time-invariant LDPC convolutional codes

2010 IEEE International Symposium on Information Theory, 2010
In this paper we present an attractive alternative to construct time-invariant Low-Density Parity-Check Convolutional Codes (LDPC-CC) of coding rate-b/c from a simple recursive systematic convolutional encoder design. The proposed Recursive Convolutional Doubly-Orthogonal (RCDO) encoders have a corresponding Tanner graph for which the girth is ...

Signal Codes: Convolutional Lattice Codes

IEEE Transactions on Information Theory, 2011
The coded modulation scheme proposed in this paper has a simple construction: an integer sequence, representing the information, is convolved with a fixed, continuous-valued, finite impulse response (FIR) filter to generate the codeword - a lattice point. Due to power constraints, the code construction includes a shaping mechanism inspired by precoding

New Convolutional Codes--Part I

IEEE Transactions on Communications, 1975
This paper is the last part of a three-part series on threshold decoding new convolutional codes. The first part of this paper concludes the list with new rate 1/2 codes. For these codes a characteristic equation, in terms of the number of correctable errors and code constraint length, is derived by least square approximations.

Code synchronization for convolutional codes

Proceedings of Canadian Conference on Electrical and Computer Engineering CCECE-94, 1994
A code synchronization technique for convolutional codes is presented which can provide improved performance at low signal-to-noise ratios. The algorithm is based on extracting evidence in support of the in-sync or off-sync hypothesis using the metric distribution within the Viterbi decoder.
