<P>PROBLEM TO BE SOLVED: To provide techniques for performing acquisition of packets. <P>SOLUTION: First detection values are determined based on a first plurality of samples, e.g., by performing delay-multiply-integrate on the samples. Power values are determined based on the first plurality of samples, e.g., by performing multiply-integrate on the samples. The first detection values are averaged to obtain average detection values. The power values are also averaged to obtain average power values. Whether a packet is present is determined based on the average detection values and the average power values. Second detection values are determined based on a second plurality of samples. The start of the packet is determined based on the first and second detection values. A third detection value is determined based on a third plurality of samples. A frequency error of the packet is estimated based on the first and third detection values. <P>COPYRIGHT: (C)2013,JPO&INPIT |
