Abstract: A communications system includes a multiple-input/multiple-output (MIMO) architecture for high capacity switched mesh networks. The MIMO architecture has a plurality of radio frequency chains. One of the plurality of radio frequency chains is configured to apply a first frequency offset to a base frequency of an output signal to generate a first transmitting frequency; and another of the plurality of radio frequency chains being configured to apply a second frequency offset to the base frequency to generate a second transmitting frequency. The system uses the carrier frequency offset to lock the clock of the master subsystem to the clock of the slave subsystem, thereby enabling bandwidth expansion to be employed on the MIMO data streams.

Abstract: A game apparatus controls a game in which a user-controlled character and an opponent character hit a ball. A serve control unit receives the first input operation from a user and makes the character perform an action of tossing the ball when the character performs a serve. The serve control unit receives the second input operation from the user and makes the character perform an action of the serve. The serve control unit determines a ball power or ball speed in the serve based on the first input operation, and determines a shot type in the serve based on the second input operation. The serve control unit makes the character perform the serve according to the determined ball power or ball speed and the determined shot type.
