Title:
DECODING IMPLEMENTATION METHOD FOR BLUETOOTH RECEIVER
Document Type and Number:
WIPO Patent Application WO/2022/099967
Kind Code:
A1
Abstract:
Disclosed in the present invention is a decoding implementation method for a Bluetooth receiver. The method comprises: setting a first length threshold and a second length threshold; performing decoding traceback on a first FEC module, and outputting a coding indicator and an access address of the first FEC module; determining, according to the coding indicator, whether a second FEC module needs to be despread; matching the access address with an actual address, if the matching succeeds, waiting to decode the second FEC module, and if the matching does not succeed, resetting a Bluetooth receiver; storing a survivor path of the second FEC module to an SMU, and in the case that the length of data stored in the SMU reaches the first length threshold, performing decoding traceback on the data stored in the SMU, outputting bit information, and extracting the length of a packet payload in a packet header from the time when the time value is the same as the length value of check data; and determining, according to the length of the packet payload, whether the total number of bits of the second FEC module exceeds the second length threshold to complete decoding.
