<p>A fading correlation monitoring section (103) detects the angular spread of a communication terminal (200-1) based on a received signal and compares it with a preset threshold value. If an estimated angular spread is smaller than the threshold value, interference wave is suppressed by performing directivity reception at an AAA receiving circuit (106) and directivity transmission at an AAA transmitting circuit (122). If the estimated angular spread is larger than the threshold value, distortion of signal due to fading is compensated by performing diversity reception at a diversity receiving circuit (107) and diversity transmission at a diversity transmitting circuit (123). Radio communication can be performed with good communication quality even when fading correlation is low.</p> |
