Patent ID: 8781032

Claim:
A communication apparatus, comprising: two or more receiving units differing in characteristics from one another; a selecting unit selecting one out of said two or more receiving units; and a data detecting unit that detects data to be received, in an input signal, the data to be received being packet data; wherein the selecting unit selects one out of the two or more receiving units based upon a result of detection by the data detecting unit and based upon the characteristics of the receiving units, the communication apparatus is a wireless communication apparatus, when the packet data is included in the input signal, the selecting unit selects one of the receiving units from which a most satisfactory reception quality is expected to be obtained depending upon propagation environments of wireless signals, when the data detecting unit fails in decoding a control channel of wireless communication a first preset number of times consecutively, the data detecting unit decides that there is no data to be received, and when the data detecting unit succeeds in decoding the control channel a second preset number of times consecutively, the data decoding unit decides that there is data to be received, the first preset number of times being greater than the second preset number of times.
