TRANSMISSION SYSTEM AND RECEIVER WITH IMPROVED DETECTION, AND IMPROVED DETECTION METHOD

摘要

In a transmission system digital symbols are transmitted by a transmitter (2) via a channel (8) to a receiver (10). The receiver (10) comprises a first detector (14) and a second detector (20) with different decision levels. In the case of an unreliable input signal of the detectors (14 and 20), the sequences of detected symbols at the outputs of the detectors (14 and 20) may differ. By checking the sequences of digital symbols on code rule violations, the most likely sequence of detected symbols can be selected by a selector (46) and passed to the output.
