Space diversity receiver

A space diversity receiver including first and second reception antennas that receive packet data in which a predetermined frame synchronous pattern is inserted in every fixed period to be compared with the predetermined frame synchronous pattern so that whether to employ the packet data received by said first antenna or to employ the packet data received by said second antenna is determined, comprising

• first and second shift-registers which store a frame synchronous pattern of the packet data received by said first and second reception antennas, respectively;
• first and second exclusive NOR circuits in which the first and second frame synchronous patterns stored in said first and second shift-registers are compared with the predetermined frame synchronous pattern, respectively;
• first and second adders which count the output of said first and second exclusive NOR circuits, respectively:
• and
• a data selector which compares the output value of said first and second adders and supplies to the receiver the packet data received by the reception antenna having a larger output value.
