A communication device of the present invention includes a physical layer for performing close-range one-to-one communication with a device of a communication counterpart by electric field coupling or magnetic field coupling; one or a plurality of PCL Emulations for converting a protocol of a higher level application to a protocol for communicating at the physical layer; and a PCL common for performing negotiation with the device of the communication counterpart without the higher level application started after the connection with the communication counterpart is established or at the same time as the connection establishment to select one PCL Emulation.

Communication device, communication system, communication method and program

Disclosed is a wireless communication apparatus for receiving a code-spread transmission signal. The wireless communication apparatus includes: an RF section; and a baseband section, wherein, in the baseband section, despreaders of an integral submultiple, which is 1/n, of the number of chips of a spread code are arranged in parallel, and there is provided a propagation measurement section that measures a propagation channel by using the plurality of despreaders a plurality of times in a time-division manner and performing despread of each period corresponding to a chip rate of the spread code.

Wireless communication apparatus, wireless communication method, propagation measurement apparatus and propagation measurement method

Disclosed herein is a wireless communication device which includes an RF processing unit and a baseband unit that carries out carrier tracking based on a signal after RF processing, in which the device includes: a phase error measuring means that measures a phase error estimation value composed of the phase error value of a carrier and the direction thereof; and a phase error correcting means that compares a phase error estimation value with a first threshold value and a second threshold value larger than the first threshold value, and carries out a first or a second phase error correcting process in response to that a phase error estimation value has exceeded the first or second threshold value.
