Abstract
In the conventional diversity reception, information included in each non-selected signal does not contribute to an improvement in the reliability of communications, and transmitting power has been dissipated to satisfy required communication quality. Owing to the setting of encoding in respective base stations to injection, signals each including the same contents, which are received by a mobile station, are used for increasing the reliability of communications without depending on the number of the signals which were capable of being received by the mobile station, to thereby reduce transmitting power for satisfying required communication quality.
Claims3
A wireless communication apparatus comprising:
- a plurality of wireless transmitting stations each provided with a transmitting antenna, a transmitter capable of transmission through a radio channel which is pre-specified, an encoder for performing encoding processing corresponding to the radio channel, and a data input interface for obtaining data to be transmitted from an external device;
- and
- a wireless receiving station including:
- a receiving antenna;
- a receiver capable of independently receiving signals from a plurality of radio channels;
- a plurality of buffers for storing received data respectively therein according to the plurality of radio channels for receiving the received data;
- a selector A for reading the received data from the plurality of buffers and sending the receiving data to either one of a plurality of decoders and a data combiner according to the buffers subjected to the reading;
- the data combiner for combining the received data in predetermined order;
- the plurality of decoders for respectively executing predetermined decoding processes;
- a selector B for selecting decoded data in interlock with the selector A and outputting the same therefrom;
- and
- a data output interface for supplying the received and decoded data to an external device.
