Improvement manner of the transmission system and the receiver, and the detection performance which improve detection performance

摘要

(57) Abstract In the transmission system, digital symbol through the channel (8), directing to the receiver (10), it is transmitted by the transmitter (2). The receiver (10), the 1st detector (14) which has the detection level which differs and, has the 2nd detector (20). Concerning the input signal reliability of the detector (14,20) to be low, the sequence of detection symbol probably will differ at the time of outputting the detector (14,20). With the selector (46) be able to choose the sequence where the symbol which is detected by checking the digital symbol sequence of code rule violation, is most desirable, and it is possible to convey to output.
