Concatenation is a method of building long codes out of shorter ones; it attempts to meet the problem of decoding complexity by breaking the required computation into manageable segments. Concatenated Continuous Phase Frequency Shift Keying (CPFSK) facilitates powerful error correction. CPFSK also has the advantage of being bandwidth efficient and compatible with non-linear amplifiers. Bandwidth efficient concatenated coded modulation schemes were designed for communication over Additive White Gaussian Noise (AWGN), and Rayleigh fading channels. Analytical bounds on the performance of Serial Concatenated Convolutional Codes (SCCC), and Parallel Concatenated Convolutional Codes (PCCC), were derived as a base of comparison with the third category known as Hybrid Concatenated Trellis Codes scheme (HCTC).
