US 2013/0093635 A1 · MODAL ADAPTIVE ANTENNA USING PILOT SIGNAL IN CDMA MOBILE COMMUNICATION SYSTEM AND RELATED SIGNAL RECEIVING METHOD

Abstract

One or more input signals are used to generate a Pseudo noise generator and re-inject the signal to obtain a more efficient method of control of a receiver using adaptive antenna array technology. The antenna array automatically adjusts its direction to the optimum using information obtained from the input signal by the receiving antenna elements. The input signals may be stored in memory for retrieval, comparison and then used to optimize reception. The difference between the outputs of the memorized signals and the reference signal is used as an error signal.

Claims6

Dependent claims

A modal antenna system comprising:

a modal antenna, comprising:
an antenna radiator disposed above a circuit board to form an antenna volume therebetween, a first frequency tuning parasitic element connected to said circuit board and positioned between the circuit board and the antenna radiator within the antenna volume, and a second beam steering parasitic element positioned outside of the antenna volume and adjacent to the antenna radiator;
and
a memory-enhanced spatial filter for use with the modal antenna;
wherein a bank of said input radio signals is stored in said memory and used for enhanced signal processing for use with a single modal antenna.
