Title: Adaptive filter for transmit leakage signal rejection
Inventor: APARIN VLADIMIR
IPC: H04B1/52
Filed: 2004-11-15
Abstract: An adaptive filter suitable for fabrication on an RF integrated circuit and used for transmit (TX) leakage rejection in a wireless full-duplex communication system is described. The adaptive filter includes a summer and an adaptive estimator. The summer receives an input signal having a TX leakage signal and an estimator signal having an estimate of the TX leakage signal, subtracts the estimator signal from the input signal, and provides an output signal having the TX leakage signal attenuated. The adaptive estimator receives the output signal and a reference signal having a version of the transmit signal, estimates the TX leakage signal in the input signal based on the output signal and the reference signal, and provides the estimator signal. The adaptive estimator may utilize an LMS algorithm to minimize a mean square error between the TX leakage signal in the input signal and the TX leakage signal estimate in the estimator signal.

IPC: H01L31/042
Filed: 2006-03-03
Abstract: Disclosed is a multilayer organic solar cell having a structure wherein an adhesive layer (3) is arranged between a first power generation layer (1) and a second power generation layer (2). This structure is obtained by forming the adhesive layer (3) on the first power generation layer (1) which is formed from an organic compound solution containing a donor material and an acceptor material, and then applying an organic compound solution containing a donor material and an acceptor material over the adhesive layer (3) for forming the second power generation layer (2). The adhesive layer (3) is composed of at least either of a transparent oxide and a transparent nitride. By having such a structure, the adhesive layer (3) prevents the solvent in the solution for the second power generation layer (2) from permeating into the first power generation layer (1) when the second power generation layer (2) is formed over the first power generation layer (1) by applying the solution. Consequently, the first power generation layer (1) is prevented from destruction or deterioration in functions.
