The disclosure describes techniques for reducing adverse effects of second order distortion and cross-modulation distortion of transmit signal leakage from a transmitter via a duplexer.
The present invention relates generally to a method and apparatus for cross modulation compensation in RF devices giving rise to cross modulation.
The cross modulation experienced by the test signal is measured, and the result hereby obtained is used for cross modulation compensation of the wanted signal at the RF device output.
An electronic circuit is used for correcting cross modulation distortion.
Therefore cross modulation due to the grain adjusting mechanism of limiter type can be reduced.
A test signal as well as a wanted signal are applied to the RF device in which cross modulation appears.
In this manner, the effect of crossmodulation on the received signal is reduced.
Crossmodulation distortion is detected from multiple bands (34) on a film (12).
Disclosed herein is a method of up-conversion of all-optical signal through cross-gain modulation in a semiconductor optical amplifier and an apparatus thereof.
Polaristion decouplers (XPIC-VH, XPIC-HV) which compensate cross-polar crosstalk between the two received signals (EH, EV) are provided for both of the receiving branches.
An optical amplifier has the characteristics of cross-gain modulation, amplifies the deviation-compressed interference signal light, and outputs the amplified interference signal light.
The equipment selected has been the PROMAX Digital To TV (DTTV) head-end, which is very flexible thanks to the several transmodulation modules available.
The input of the semiconductor amplifier (4) is connected to the first laser light source (L1) and the modulation input of the semiconductor amplifier (4) is connected to the signal input for cross-amplification modulation.
