Flexible blocks for high throughput serially concatenated convolutional codes
Proceedings of the 17th ACM Great Lakes symposium on VLSI, 2007Modern communication systems aim to integrate different services including telephony, multimedia applications and data transfer. This integration imposes to design flexible systems, able to support different frame duration and data-rates. In this paper we present several blocks employed in serially concatenated convolutional codes and we detail some ...

Design of rate-compatible punctured serial concatenated convolutional codes
2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577), 2004A new design criterion to obtain well performing rate-compatible serial concatenated convolutional codes (SCCC) families is proposed. To obtain rate-compatible SCCCs, the puncturing is limited to inner coded bits. However, the puncturing is not restricted to inner parity bits, but extended also to inner systematic bits, thus obtaining high rate SCCCs ...

Serial concatenation schemes for space-time and recursive convolutional codes
The 57th IEEE Semiannual Vehicular Technology Conference, 2003. VTC 2003-Spring., 2004Serial concatenation scheme with a space-time trellis code as the outer code and recursive convolutional codes as the inner code are compared. A new encoding/decoding structure characterized by the inner encoding by a single recursive convolutional code and the combined decoding of simultaneous symbols from multiple antennas is proposed, which gives a ...

Iterative decoding of serially concatenated convolutional codes applying the SOVA
VTC '98. 48th IEEE Vehicular Technology Conference. Pathway to Global Wireless Revolution (Cat. No.98CH36151), 2002In numerous researches, the soft output Viterbi algorithm (SOVA) has been used for the iterative decoding of a parallel concatenated convolutional code (PCCC) instead of the maximum a posteriori (MAP) decoding algorithm having a suboptimal bounds to the maximum likelihood (ML) performance.

2010 IEEE International Conference on Communications, 2010
In this paper, we focus on the design of optimized binary convolutional codes (CCs) and serially concatenated convolutional codes (SCCCs) in the presence of a-priori information (API) at the receiver. First, we propose a design criterion for CCs based on the minimization of the bit error proabability (BEP).

Serially concatenated continuous phase modulation with convolutional codes over rings
IEEE Transactions on Communications, 2006In this paper, we investigate serially concatenated continuous phase modulation (SCCPM) with convolutional codes (CC) over rings. The transmitted signals are disturbed by additive white Gaussian noise. The properties for systems with both infinite and finite block lengths are investigated.

Serially concatenated convolutional coding for an optical PPM/CDMA system
The 6th International Conference on Advanced Communication Technology, 2004., 2004In this paper, performance of on optical PPM/CDMA system with SCCC is analyzed and simulated. It is assumed that optical channel is on intensity modulated (IM) channel and direct-detection scheme is employed to defect the received optical signal. The modulation scheme used is pulse-position-modulation (PPM). The performance is evaluated in terms of bit

Serial Concatenated Convolution Codes for Coded OFDM in Digital Audio Broadcasting Environment
2019 International Conference on Intelligent Sustainable Systems (ICISS), 2019In this paper, we are simulating the Bit Error Rate (BER) for computerized Digital Audio Broadcasting (DAB) framework that utilizes Co-OFDM system by parallel and serial coding schemes. Serial convolution coded data appears to be an Additive White Gaussian Noise (AWGN) Channel that is dependent on various imperative constant dimensions and code ...
