Abstract: PROBLEM TO BE SOLVED: To provide a broadcast relay station device and a sneak path cancellation method that can enhance the follow up ability of a sneak path transmission line characteristic due to temporal fluctuations by reducing a cancellation residue so as to stably attain cancellation. SOLUTION: A transmission line characteristic prediction section 331 estimates the characteristic of a transmission line when a signal sent from a transmission antenna 5 is sneaked to a reception antenna 1 and the characteristic of the transmission line in a succeeding control unit is predicted on the basis of the result of estimate. A filter coefficient generating section 334 generates a filter coefficient on the basis of the result of prediction and a FIR filter 35 filters the filter coefficient to generate a copy signal of the signal sneaked to the reception antenna 1. A subtractor 31 subtracts the copy signal from the received signal to eliminate the interference due to the sneak path.

Accordingly, the surface emitting LDs 12 are rotated, the polarization directions of all of the light emitting points change at the same time. The transmissivity of light can be changed by an optical unit. Even if the light quantity is the same, the dynamic range of the light quantity on the photoreceptor can be made larger. Also, the intervals in the vertical scanning of the light emitting points emitted before and after the rotation of the surface emitting LDs 12 are the same and therefore the spot intervals on the photoreceptor are the same. Resolution can be easily changed by selecting the light emitting points where the light is emitted.
