Maximum a Posteriori Bit-Unstuffing

Bit-stuffing is the procedure of introducing an extra bit in the transmitted stream after a fixed number of consecutive ones or zeros.

Description
Summary:Bit-stuffing is the procedure of introducing an extra bit in the transmitted stream after a fixed number of consecutive ones or zeros. This paper demonstrates that, for conventional unstuffing, the BER experienced by individual bits within a stuffed frame dramatically and monotonically degrades with its positional-index. We also show that when knowledge of the number of stuffed bits is applied to maximum a posteriori (MAP) bit-unstuffing (MAPBU) (through a BCJR algorithm), this trend is significantly mitigated.
