Performance of Heuristic Algorithms in minimizing BER for Robust Turbo Codes
The third component introduced in conventional turbo codes in recent days is effective in improving the performance of the code. But under noisy environments the parameters such as permeability and permittivity rates are static and hence their adapatability to noisy environment is poor. To overcome the aforesaid drawback A3D-TC was proposed in our previous paper[29].In our present paper a compa...
متن کاملImproving BER using turbo codes in OFDM systems
Orthogonal Frequency Division Multiplexing (OFDM) has been successfully applied to a wide variety of digital communication applications over the past several years. OFDM is a suitable candidate for high data rate transmission with forward error correction (FEC) methods over wireless channels. OFDM is a suitable candidate for high data rate transmission with forward error correction (FEC) method...

Optimized BER Performance of Asymmetric Turbo Codes over AWGN Channel
The performance of the turbo codes can be improved by varying parameters such as block size, code polynomial structure and constraint length. This paper proposes a new asymmetric turbo codes that consists of parallel concatenated component codes with mixed type generator polynomials and also different constraint lengths. This scheme optimizes the BER performance of asymmetric turbo codes of bot...
متن کاملImproving the Constituent Codes of Turbo Encoders
The performance of Turbo codes can be improved by choosing the best constituent encoder. Previous lists of the best constituent codes were found based on maximising the input weight two effective free distance d 2. We show that minimis-ing the number of nearest neighbours N 2 is also an important requirement. If there are multiple codes having the same d 2 and N 2 , we show that the minimum dis...
