Built-in test system and method

摘要

A communication device includes a DC input component, a transmitting component an envelope detecting component, a receiving component, a storage component and a comparator. The DC input component generates a first direct current signal and a second direct current signal. The transmitting component generates a first transmitted signal based on the first direct current signal and a second transmitted signal based on the second direct current signal. The envelope detecting component generates a first envelope signal based on the first transmitted signal and generates a second envelope signal based on the second transmitted signal. The receiving component generates a first received signal based on the first envelope signal and a second received signal based on the second envelope signal. The storage component has a priori information stored therein. The comparator outputs a correlation signal based on the first received signal, the second received signal and the a priori information.
