摘要：in digital communication systems, channel coding is the method of adding redundancy to the data in order to reduce the frequency of errors or to increase the capacity of a channel. Concatenated codes are the most superior class of codes making achievable channel capacity almost at par with the Shannon limits. Concatenated codes are error correcting codes constructed by combining two or more simple codes through an interleaver in order to obtain powerful coding schemes. In this paper a special construction of concatenated convolutional coding scheme called parallel-serial concatenated convolutional code (P-SCCC) is presented. The upper bound to the bit error probability of the proposed code is evaluated. Results showed that the error performance of this proposed code scheme is better than that of both classical serial and parallel concatenated convolutional codes. The performance of the proposed code has been studied with different types of digital modulation schemes
