Orthogonal frequency division multiplexing receiver with low-resolution analog to digital converter and electronic device thereof

An electronic device comprising:

• a processor;
• and
• an OFDM receiver comprising:
• 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 directly output an estimated transmission signal, wherein the signal estimating module comprising:
• a s-estimator which calculates the estimated transmission signal from the estimated error signal and the channel attenuation coefficient of the channel based on performing a minimum mean square error (MMSE) calculation or a zero forcing (ZF) calculation.
