Abstract:
The disclosure is directed to an OFDM receiver with a low-resolution ADC and an electronic device thereof. According to one of the exemplary embodiments, the OFDM receiver may include not limited to: an ADC module which receives a transmission signal of a channel in an analog format and digitizes the transmission signal into a digital format to generate a quantized transmission signal; an error compensating and estimating module which is coupled to the ADC module, receives the quantized transmission signal and a feedback signal which is a first estimated time-domain transmission signal to generate an estimated error signal according to a turbo iterative updating technique; and a signal estimating module which is coupled to the error compensating and estimating module, receives the estimated error signal and a channel attenuation coefficient of the channel to generate an estimated transmission signal.
