Enhancement of Voice Quality and System Capacity by Error Detection and Correction Method in Wireless Digital Communication

Error detection and correction are critical components of any wireless digital communication system. In wireless digital communication, an error detection and correction method is used to detect and correct errors that occur in the transmission of digital data, such as in the case of network packets or other digital data transmissions over a wireless channel. The most common error detection and correction methods in use today are cyclic redundancy check (CRC) and forward error correction (FEC) schemes. The CRC scheme uses a cyclic redundancy code to detect errors in a digital transmission, while the FEC scheme uses forward error correction algorithms to recover lost or corrupted data. While both methods can effectively detect and correct errors, the CRC scheme is often preferred due to its simple implementation and low complexity. FEC schemes, on the other hand, are more intensive in terms of processing and require more sophisticated hardware for implementation.
