Demodulation frames, often referred to as demodulation packets or demodulation envelopes, are fundamental components in the process of demodulation, which is the extraction of the original signal from a modulated carrier wave. These frames serve as structured containers for the data that is being demodulated, ensuring that the information is accurately and efficiently processed.

Demodulation frames typically include several key elements. The preamble, which is a sequence of known symbols or bits, is used for synchronization purposes. This helps the demodulator to align its timing with the incoming signal. The payload section contains the actual data that is being demodulated, while the cyclic redundancy check (CRC) or error detection code is used to verify the integrity of the data. Some frames may also include a header that provides additional information about the frame, such as the length of the payload or the type of modulation used.

The structure and format of demodulation frames can vary depending on the specific communication system or protocol being used. However, they all serve the same basic purpose: to provide a standardized way of organizing and transmitting demodulated data. By using demodulation frames, communication systems can ensure that the data is accurately and efficiently processed, even in the presence of noise or other interference.
