Rate adaptation refers to the process of adjusting the transmission rate of a communication system based on various factors such as network conditions, signal quality, and interference levels. This adaptive technique allows for optimal utilization of available bandwidth and ensures efficient data transmission. Rate adaptation algorithms are commonly used in wireless communication systems to dynamically vary data rates in real-time, in order to maintain a reliable and high-quality connection. The goal of rate adaptation is to maximize throughput while minimizing errors or packet loss during communication.
