Forward Error Correction Support in WirelessUSB-NL - KBA82944

Last Updated: 10/11/2012
Version: **
Question: Does WirelessUSB-NL support forward error correction (FEC)?

Answer: Yes. WirelessUSB-NL has the FEC23 encoder that adds redundancy to the transmit data, using 3 bits to transmit every two payload bits. Therefore, it increases the packet transmit time and effective receive sensitivity, and decreases the receive bit error rate (BER) decrease, thereby increasing the operational range and interference immunity.

How to enable/disable:

To enable/disable FEC, register 32 (bytes b4 and b5) can be programmed with the following options:

FEC_TYPE
00b: No FEC
01b: Reserved
10b: FEC23
11b: Reserved
