Title: Echo canceller and training method for the echo canceller
Inventor: FUKUTO YUICHI
IPC: H04J11/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory echo suppression characteristic, even in the case of full duplex communication in an echo canceller for a transmitter and a receiver in multi-carrier modulation system. SOLUTION: An echo replica generating section 2 consists of an adaptive filter of transversal type and generates an echo replica signal of a bypass signal of a transmission signal from the transmission signal. A 1st adder 3 subtracts the echo replica signal from a received signal. When a prescribed training pattern is sent from an opposite side device, a mean value calculation section 5 obtains a means value of outputs of the 1st adder 3 and provides an output of it, and when a pattern is received other than the training pattern, the section 5 outputs zero. A 2nd adder 4 subtracts the output of the means value calculation section from an output of the 1st adder.  Then a switch 6 supplied an output of the 2nd adder to the echo replica generating section for its tap coefficient update as an echo residual, and when the output of the mean value calculation section is zero, the echo residual is set to zero.

Abstract: PURPOSE:To improve reliability by increasing a laser output light corresponding to contamination of a condensing lens. CONSTITUTION:When a condensing lens 14 is not contaminated, pit data is previously recorded on a recording medium 13, and data 24 is reproduced each time new data is recorded. A reflected light 1 is photoelectrically converted by a diode 2 and then into a reproduced signal 26 by a circuit 3, and an amplitude value H1 is stored in a memory 5. Similarly, data 25 is reproduced to become a signal 27, and an amplitude Hz is stored in a memory 6. A comparator 7 relatively compares the amplitude H1 with that H2 so as to ignore contamination of the lens 14, and outputs a signal of contamination of the lens 14 when it becomes a predetermined value or more. A comparison output of the comparator 7 is sent to a controller 12, and an output light 8 of a semiconductor laser 9 at the time of recording is controlled through the controller 13 and a record driving current circuit 11. Thus, recording/reproducing in which the influence of contamination of the lens 14 is corrected can be performed, and the reliability of the control can be enhanced.
