摘要
A novel synchronous baseband receiver is presented in this letter. With a pilot tone insertion at the transmitter, the proposed baseband receiver can perform carrier recovery (CR) regardless of modulation scheme and/or baud rate. The synchronous baseband receiver has an analog-digital hybrid structure, where a low-cost digital signal processor controls an analog local oscillator (LO) in frequency and phase to achieve CR. This structure requires only one low-cost analog-to-digital converter (ADC) with a sampling rate of 100 MS/s. A proof-of-concept demonstration at E-band achieves 9-Gb/s 64-quadratic-amplitude modulation (QAM) and 16-Gb/s QPSK transmissions.
