Abstract
A wireless network uses an improved frame structure to increase timing acquisition capabilities as well as reduction of spectral lines. In one aspect, the frame packet can be used to communicate the different modes of operation under which the packet was created.
Claims26
A method of communication, comprising:
- selecting different Golay codes to include for each of a plurality of data blocks;
- dividing a payload of a packet into the plurality of data blocks, wherein each data block comprises Golay codes and data portions, and every data portion of a data block is between two of the Golay codes selected for that data block;
- inserting information between two successive data blocks of the plurality of data blocks, said information comprising at least two different Golay codes and enabling at least one of time, channel and frequency estimation;
- and
- transmitting the packet.
