Title: Receiver
Inventor: SHIMAMURA SATORU
IPC: H04J11/00
Filed: 2000-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a receiver with a small circuit scale without requiring a complex coefficient filter for the estimation of a transmission line response by a pilot signal. SOLUTION: The transmission line response of the pilot signal is calculated and a high-speed inverse Fourier transform is performed in a inverse Fourier transform (IFFT) part 17 to determine a time response, then only the main incoming wave more than a threshold is restricted. The output of the IFFT section 17 is weighted according to the size of amplitude of the main incoming wave in a delay time deciding part 18, and the center value of the time response is determined by equalizing. Rotators 19 and 20 are controlled from the determined center value, and the time response of the pilot signal is made positively and negatively symmetrical. Thereby, the transmission line response of all subcarriers can be estimated by using a band changeable filter 22 having a real coefficient. Thus, the complex coefficient filter is not required.

Title: Reader/writer for non-contact ic card
Inventor: TAKAHASHI KIYOSHI
IPC: B42D15/10
Filed: 2000-04-28
Abstract: PROBLEM TO BE SOLVED: To communicate with an IC card by plural communication systems and communication rates in accordance with a command from a host device. SOLUTION: This reader/writer 1 transmits an initial command by a communication system 2 following an initial command by a communication system 1 in response to a command from the host device 2. Since the IC card in the system 2 positioned in a communication area makes a response then, the fact is sent back to the host device 2. After then, communication with the IC card 3 is performed by the system 2. Then, the reader/writer 1 transmits the initial command of the system 1 in the case of detecting whether the IC card 3 of the system 1 exists or not in response to the command from the host device 2 in a communicating state with the IC card 3 in the system 2. Since there is no response from the IC card 3 then, the reader/writer 1 sends the fact to the host device 2 and switches the system to the system 2 to restart communication with the IC card 3 in the system 2.
