METHOD FOR DETERMINING TUNING FREQUENCY OFFSET IN RECEIVER FOR GENERATING COMPLEX DATA SAMPLE FROM DEMODULATED RECEPTION SIGNAL, AND WIRELESS LAN RECEIVER |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method and a receiver for realizing reliable preamble detection even on an extreme radio channel condition. <P>SOLUTION: A real number sample I and an imaginary sample Q from a converter are given to the 64-sample delay circuit 702 of a preamble processing circuit. The delay circuit 702 has several taps for leading a sample to be delayed by sampling periods 0, 16, 32 and 64 from 64 continuous samples sent to the circuit. This delay circuit 702 is used for all of three functions. <P>COPYRIGHT: (C)2003,JPO |
