Abstract

본 발명은 데이타 수신장치에서 수신되는 데이타를 복원한 후 복원된 데이타의 에러율을 검출하여 수신 신호의 강도로 표시한다. 이를 위하여 먼저 수신되는 변조신호를 복조한 후, 복조신호를 디지탈 형태의 펄스 신호로 파형정형한다. 그리고 이러한 펄스신호의 위상을 고정시켜 동기신호를 검출하고, 상기 동기신호를 기준으로 데이타를 복원한다. 그러면 복원 데이타로부터 특정 데이타의 상태를 분석하며, 분석된 데이타의 에러를 검출하여 에러율에 대응하는 수신강도신호로 변환 출력한다. 이로인해 주변 간섭의 영향에 의한 신호 강도의 오류를 디지탈신호의 강도신호로 표시한다.The present invention detects the error rate of the restored data after restoring the data received by the data receiving apparatus and displays the received signal strength. To this end, first, the demodulated signal is demodulated, and then the demodulated signal is waveform-shaped into a digital pulse signal. The phase of the pulse signal is fixed to detect a synchronization signal, and data is restored based on the synchronization signal. Then, the state of the specific data is analyzed from the restored data, and the error of the analyzed data is detected and converted into a received intensity signal corresponding to the error rate. As a result, an error in signal strength due to the influence of ambient interference is represented as a digital signal strength signal.
