[0108] Figure 5 is a block diagram showing the configuration of a digital broadcast receiving apparatus 10A according to the present first embodiment.

[0109] Although the transmission mode may vary by region or broadcast station, etc., this embodiment assumes that it is mainly used in a fixed reception environment such as a home when the transmission mode does not change for a short period of time such as one program unit. .

[0110] exist Figure 5 In this case, an antenna 101 supplies a digital broadcast signal to an input terminal of a tuner 102 . This tuner 102 selects a signal of a channel selected by a user from digital broadcasting signals supplied from the antenna 101, converts the frequency of the signal from a radio frequency band to a base frequency band, and supplies an output to an input terminal of an OFDM demodulation section 103. OFDM demodulation section 103 applies processing such as demodulation and error correction to digital broadcasting signals of the...

Abstract

The invention provides a portable terminal and an access control system, wherein the portable terminal comprises: a broadcast signal receiving unit, for receiving broadcast signals; a bar code forming unit, forming a bar code; a bar code display unit, for displaying the bar code, based on data information received by the broadcast signal receiving unit, the bar code formed by the bar code formingunit, and the bar code formed by the bar code display unit.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of December 6, 2001, an application number of "01822104.1", and an invention title of "Orthogonal Frequency Division Multiplexing Signal Receiving Device". technical field [0002] The present invention relates to an OFDM signal transmission system for digital terrestrial broadcasting, and electronic commerce utilizing communication. Background technique [0003] Regardless of the type of transmission path such as satellite, cable, and terrestrial, program broadcasting is increasingly being digitized all over the world in recent years. Among these digital broadcasting systems, the European and Japanese digital broadcasting systems use an Orthogonal Frequency Division Multiplexing (hereinafter referred to as "OFDM") transmission system. [0004] An OFDM transmission system modulates a plurality of carriers orthogonal to each other with information to be transmitted in eac...
