摘要： Before start of streaming, a server apparatus obtains from client apparatuses their respective numbers of antenna combinations, determines a training time t1 according to the maximum of the numbers of antenna combinations, and notifies the client apparatuses of the training time t1. Each client apparatus determines a training time t2 required to estimate transmission path conditions for one antenna combination, based on the training time t1. The server apparatus transmits a training signal during the training time t1. Each client apparatus estimates transmission path conditions using the training signal during the training time t2 for each antenna combination, and selects and sets an antenna combination based on the estimated transmission path conditions.

摘要： A steerable antenna includes an radiating antenna element and parasitic antenna elements. Each of the parasitic antenna elements is provided with a pair of PIN diodes. On each of control lines connecting the PIN diodes to a controller, inductors are provided at predetermined intervals on portions of the control line electromagnetically coupled to another steerable antenna. The intervals for providing the inductors is set to such a length that substantially no resonance occurs in a section of the control line between the inductors at an operating frequency of the steerable antenna.
