WIRELESS RECEIVER
First Claim
1. A wireless receiver, which enables a main transceiver sending and receiving data upon receiving a specific identification signal, comprising:
- a signal detector for receiving a wireless signal in a predetermined frequency band, and if the received wireless signal is above a reference level, outputting a first wake-up signal; and
an identification detector, enabled by the first wake-up signal of the signal detector, for decoding a wireless signal in a predetermined frequency band with a SAW correlator, and determining whether or not the decoded signal is a predetermined specific identification signal, and if the decoded signal is a predetermined signal, outputting a second wake-up signal to enable the main transceiver.

Abstract
The invention relates to a wireless receiver which is enabled upon receiving a specific identification signal to receive data, and more particularly, which minimizes power consumption in an idle state and accurately discriminate the specific identification signal. The wireless receiver which receives the specific identification signal to enable a main transceiver for transmitting and receiving data includes a signal detector for receiving a signal in a particular frequency band to output a first wake-up signal, and an identification detector which is enabled by the first wake-up signal, decoding a signal in a particular frequency band, and discriminating whether or not the decoded signal is the identification signal to enable the main transceiver.
