We investigate the decoding technique and performance of concatenated Hadamard codes. Efficient soft-in-soft-out decoding algorithms based on the fast Hadamard transform are developed. Performance required by CDMA mobile or PCS speech services, e.g., BER = 10-3, can be achieved at Eb/N0 = 0.5 dB using short interleaver length of 198 bits.
