Abstract
A method for decoding bi-phase encoded data begins by interpreting a first bit boundary of a bit of the bi-phase encoded data to produce a first boundary value. The method continues by interpreting a second bit boundary of the bit of the bi-phase encoded data to produce a second boundary value. The method continues by comparing the first boundary value to the second boundary value to produce a decoded bit.

A decoding module comprises:
- interpreting module operably coupled to:
- interpret n-current bits of bi-phase encoded data to produce n-interpreted current bits;
- interpret a portion of a previous bit of the bi-phase encoded data to produce an interpreted previous bit portion;
- interpret a portion of a subsequent bit of the bi-phase encoded data to produce an interpreted subsequent bit portion;
- and
- a decoder operably coupled to decode the n-current bits based on the n-interpreted current bits, the interpreted preceding bit portion, and the interpreted subsequent bit portion to produce n-decoded bits.

A radio frequency identification (RFID) reader comprises:
- a radio frequency (RF) front end operably coupled to convert a received RF signal into a near baseband signal;
- a digitizing module operably coupled to convert the near baseband signal into a digital baseband signal;
- pre-decoding module operably coupled to convert the digital baseband signal into bi-phase encoded data;
- and
- a decoding module operably coupled to:
- interpret a portion of a previous bit of bi-phase encoded data to produce an interpreted previous bit portion;
- interpret a current bit of the bi-phase encoded data to produce an interpreted current bit;
- interpret a portion of a subsequent bit of the bi-phase encoded data to produce an interpreted subsequent bit portion;
- and
- decode the current bit based on the interpreted preceding bit portion, the interpreted current bit, and the interpreted subsequent bit portion to produce a decoded bit.
