Abstract
A quadrature bandpass-sampling receiver providing time diversity for OFDM is provided. A quadrature bandpass-sampling analog-to-digital demodulator down converts an OFDM signal in the RF frequency range to baseband based on a high-frequency sampling clock equal to the RF frequency and generates the in-phase and quadrature outputs in form of high-frequency bit streams. The period of the bit stream is the inverse of the OFDM carrier frequency, which is much higher than the OFDM symbol rate, allows usage of multipath diversity to improve the communication link.
