<p>A circuit for descrambling a packet transmitted frond and received in a communication device, includes (a) a plurality o~ descraniblers (1-18 to 1-2 6) each receiving words obtained by developing the packet in parallel and descrambli ng data in the words to be descrambled, each of the descraniblers being associated with a combination of addresses of the data in the words, (b) a padding numb er detector (1-7) which counts a padding number of a final words among the word s, based on data indicative of a packet length which data is included in the packet, and (c) a data selector (1-36) which selects one of outputs transmitted from the dercramblers an association with the combination to thereby receive data obtained by descrambling the words, from the thus selected descrambler.</p> |
