Message faulting is the leading cause of poor reception. Currently, most faulting in 5G and 6G requires either transmission of bulky FEC bits, or retransmission of the message, at substantial delay and cost. This paper shows how the receiver can internally (autonomously) correct the message faults by scanning the digitized waveform signals, to detect characteristic fault signatures that clearly identify the likely faulted subcarriers. With that information, and the CRC or other appended code, and optionally an AI assist, the receiver can correct the message in a fraction of the time required for a retransmission. The message is corrected instantly, with zero background generation, zero bandwidth consumption, and zero cost. Autonomous fault mitigation in the receiver is the most efficient way to improve user reception.

An active electrical element within the respective LED pixels may be constituted so as to receive the communication signal, generate a corresponding synchronization signal, and responds so as to harmonize with all the other LED elements in a specific LED display. A decrease in the number of LED pixel malfunctions in the LED strings is performed when the controller is configured accompanying a bidirectional communication port for communicating with the LED strings. In a process of reducing malfunctions, the direction of the bidirectional communication port may be changed so as to provide the communication signal in both the sides of the LED strings.SELECTED DRAWING: Figure 52
