Abstract
An apparatus and a method for transmission system are disclosed. According to an embodiment, a voltage standing wave ratio (VSWR) detection apparatus, comprising: a signal processing circuit with 1-bit analog-to-digital converter (ADC) functionality configured to receive a forward coupled signal in a transmission line of an antenna system, receive a reverse coupled signal in the transmission line of the antenna system, detect the forward coupled signal and the reverse coupled signal, convert the forward detected signal and the reverse detected signal to an analog voltage signal mapped to a return loss value, convert by the 1-bit ADC the analog voltage signal into a digital pulse train and output the digital pulse train to a digital interface of a processing device or unit.
