Title: Digital communication system receiver, computer program therefor and record medium recording the same
Inventor: YOSHIKAWA SUSUMU
IPC: H04L47/43
Filed: 2001-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a digital receiver which does not generate noises when having received a packet containing data which cannot be corrected errors. SOLUTION: In a digital communication system which sequentially transmits an analog signal by a digitized packet, a receiver 1 comprises a data processor 12 and an error detector 13. The error detector 13 detects whether or not data in the packet is erroneous. When the error detector 13 does not detect a data error in the packet, the data processor 12 reproduces data of the packet, and further when the error detector 13 has detected that the packet at a certain point of time is an unnecessary packet containing data having an error, zero level data is reproduced during a period from a point in time when data of the packet received just before the unnecessary packet is at zero crossing to a point in time when data of the packet received just after the unnecessary packet is at zero crossing.
