Abstract:
1. A method of generating a packet preamble for OFDM transmission, comprising: generating a plurality of OFDM preamble segments, wherein at least one of the OFDM preamble segments comprises a plurality of sample values; grouping a first subset of the OFDM preamble segments into a first section of contiguous OFDM preamble segments of a first part of the packet preamble so that similar OFDM preamble segments are included in the first section; and grouping a second subset of the OFDM preamble segments into a second section of contiguous OFDM preamble segments of the first part of the packet preamble so that some of the OFDM preamble segments included in the second section are non-similar and some of the OFDM preamble segments included in the second section are also included in the first section so that the first and second sections overlap.
