Abstract
A coded pilot assisted high data rate millimeter-wave receiver topology is presented in this article. A low data rate and low power pseudorandom noise (pn) coded pilot signal is superimposed at the transmitter, and the receiver can use such pilot for carrier recovery (CR) and/or channel estimation regardless of modulation scheme or communication data rate. The proposed baseband receiver has an analog–digital hybrid structure where a low-cost digital signal processor is used. This structure requires only a low-cost analog-to-digital converter (ADC) with a sampling rate of 40 MSPS. A proof-of-concept communication link at $E$ -band is demonstrated with 18 Gbps 64-quadrature amplitude modulation (QAM) and 24 Gbps 16-QAM.
