A new technique, called the code comparing technique, is applied to the type-I hybrid ARQ scheme using sequential decoding with code combining (Kallel and Haccoun 1988); and throughput analysis of this scheme is performed for the SW mode. If the correct data are not obtained at the end of the decoding process in the scheme proposed by Kallel and Haccoun (1988), then the code comparing technique is applied. The reason for using the code comparing technique in the scheme proposed by Kallel and Haccoun is to draw the number of erroneous bits in the combined sequence into the error correction capacity of the code when the number of erroneous bits in the combined sequence is greater than the error correction capacity of the code. The code comparing technique yields a throughput improvement over the scheme proposed by Kallel and Haccoun, especially when E(s)/N0 greater-than-or-equal-to 1 dB and E(s)/N0 is between -0.5 dB and -2 dB.
