The present invention discloses a method and device for bit stuffing for digital communication purposes. A method according to the present invention contains a process related to bit stuffing, comprising the steps of selecting n bits from a first queue forming a first-bit sequence, comparing the first bit sequence with prestored bit stuffing data and performing actions with the selected bit sequence and first queue according to data comprised in the prestored bit stuffing data. In a bit stuffing process according to the present invention a number of bits are added to a second queue and a number of bits are removed from the first queue, said bit sequences or number of bits are determined from the prestored bit stuffing data. The process of comparing the selected bit sequence with prestored data is possible to perform in all steps involved with bit stuffing, both in the transmitting process and in the receiving process, and in the during flag hunting as well as bit stuffing. In a preferred embodiment the prestored bit stuffing data is in the form of a lookup table. A device according to the invention comprises two storage means (138, 144) for the queues, a storage means (142) for the bit stuffing data and stuffing means (140) performing the selecting, comparing, adding and removing steps of the method. |
