Adaptive communication is one of the key technologies used to enhance the capabilities of future communication systems. Many adaptive bit and power loading techniques have been investigated in the literature for enhancement of transmission rate in combination with Orthogonal Frequency Division Multiplexing (OFDM). In these systems mainly either modulation or coding scheme was adaptive but not both. That is, one of the two aspects was fixed while other was adaptive e.g., adaptive modulation with fixed channel code or adaptive coding with a fixed modulation alphabet.
