Adaptive reception diversity apparatus and adaptive transmission diversity apparatus

An adaptive reception diversity apparatus, comprising:

• a plurality of antennas;
• movement direction estimating means for estimating a movement direction of a transmitting side;
• reception radiation pattern control means for providing reception signals from the antennas with reception radiation pattern;
• addition means for composing a plurality of inputs from said antennas;
• radiation pattern control means for controlling rotation of said reception radiation pattern based on an output of said movement direction estimating means;
• decision means for performing hard decision of an output of said addition means;
• and
• error detecting means for detecting an error between an output of said decision means and the output of said addition means, and feeding back the error to said reception radiation pattern control means.

An adaptive transmission diversity apparatus, comprising:

• a transmission radiation pattern controller that provides a transmission signal for an antenna with a first transmission radiation pattern by a first control signal;
• a movement direction estimator that estimates a movement direction of a receiving apparatus in accordance with the reception signal from said antenna;
• a radiation pattern correction controller that provides said transmission signal with a second transmission radiation pattern by a second control signal based on an output of said movement direction estimator;
• and
• a transmission signal processing system having a multiplier that multiplies said transmission signal by said first control signal and said second control signal.
