Modulation and Coding Trade-off topics include: Bandwidth efficiency, bandwidth modulation, digital communication system evaluation techniques, trellis coded modulation, amplifier techniques and entropy concepts.

Modulation is the process of changing the characteristics of a carrier wave, such as amplitude, frequency, or phase, to encode information. Coding is the process of adding redundancy or error correction to the information bits, to improve the reliability and efficiency of the transmission.

The trade-off of modulation is that the information bit rate of the communication link becomes K N , which is less than 1 information bit per code bit. This is called the rate of the code.
