Document Type and Number:
Japanese Patent JP2536207
Kind Code:
B2
Abstract:
In a cross-polarization interference canceller for use in a digital radio communication system which transmits digital modulated signals over radio frequencies having planes of polarization orthogonal to each other, signals from the interfering polarized wave are sampled with a frequency equal to double the frequency of the affected polarized wave and, after latching the sampled signals with the frequency of the symbol rate, interference cancelling signals are generated by adding the products of their multiplication with control signals. Therefore, the digital multipliers (108, 109, 110) and the digital adders (112, 114) for generating the interference cancelling signals can be operated at low speed.
