The performance of a concatenated turbo code with an outer BCH code is examined. The turbo code was based on simple 4-state constituent codes with a constrained high spread random (HSR) inter-leaver. Data puncturing, as opposed to puncturing only the parity bits, was used with the Turbo code to improve the convergence performance in the waterfall region. It is shown that this simple approach achieves performance better than the rate frac12 DVB-S2 concatenated LDPC-BCH code
