How encoding and decoding is done in wireless?

In wireless communication, encoding transforms data into a format suitable for transmission over a channel, often using techniques like modulation, error correction, and compression to enhance reliability and efficiency. The encoded signal is then transmitted through the air as electromagnetic waves. At the receiving end, decoding reverses the process, converting the received signal back into its original data format while correcting any errors that may have occurred during transmission. This process ensures that the information is accurately conveyed despite potential interference and signal degradation.
