摘要： Provided is an apparatus and method for estimating high-integration, high-speed and pipelined RLSs. Pipeline characteristics are given to an RLS algorithm to provide a high-speed HIP-RLS estimation apparatus. The HIP-RLS estimation apparatus has higher integration level than a conventional CORDIC-based RLS estimation apparatus. Thus, the use of the HIP-RLS estimation apparatus can reduce a chip size, thereby making it possible to fabricate more chips using the same wafer. Also, the HIP-RLS estimation apparatus is suitable for high-speed wireless communication because it has a high signal processing speed.

摘要： Disclosed herein is a method of providing vehicle wireless communication. In the method, a vehicle receives hand-over-related link information, which includes slot request information about slots requested by a vehicle to a roadside wireless communication device for hand-over of the vehicle, from a central control server. A hand-over preparation message, which includes the hand-over-related link information, is send to a vehicle wireless communication device connected to the vehicle. It is determined that the vehicle completed preparation for performance of the hand-over when a response message to the hand-over preparation message is received from the vehicle wireless communication device. Slots are allocated in consideration of the hand-over-related link information. Beacon frames, which include slot allocation information about the allocated slots, are transmitted to the vehicle wireless communication device. Accordingly, the vehicle wireless communication device and the roadside wireless communication device can reliably perform communication without interruption.
