his paper presents a scheme of serially concatenated codes. It is formed by Bose Chaudhuri Hocquenghem (BCH) as outer code and Low-density Parity Check (LDPC) inner code in order to real-time applications by getting rid of the delay time stem from a large number of iterations of LDPC decoder. Also analyzing the performance of each code individually by several example simulations using Matlab version R2012a tested by Additive White Gaussian Noise (AWGN) channel model with Binary Phase Shift Keying (BPSK) modulation to pick up appropriate parameters for this purpose. The proposed approach presents a high performance and reduces the Bit Error Rate (BER). Proposed parameters get nearly to zero BER at a very low Signal to Noise Ratio (SNR).
