A cognitive tri-band transmitter (TX) with a forwarded clock using multiband signaling and high-order digital signal modulations is presented for serial link applications. The TX features learning an arbitrary channel response by sending a sweep of continuous wave, detecting power level at the receiver side, and then adapting modulation scheme, data bandwidth, and carrier frequencies accordingly based...
The research uses flower auction data from KIFA to study the price formation process in Dutch auctions. Using ARIMA model, we find that the auction prices are highly correlated and the prices follow an AR(1, 0, 0) process with coefficient 0.583. Based on it, we construct multiple linear regression equations and analyze the effect of some factors on the auction prices. The result shows that the average...
