Method for transmitting data to receiving terminal in e.g. very high throughput wireless local area network system, involves generating data packet including detection fields, and data, and transmitting data packet

摘要

The method involves generating a detection field including symbols e.g. VHT-SIG1, modulated by using a binary phase shift keying (BPSK) data tone. Another detection field is generated to include symbols modulated such that an even numbered and odd numbered subcarriers have a phase difference of 90 degrees. A data packet including the former detection field and the latter detection field, and the data is generated, and the data packet is transmitted. The even numbered subcarrier and the odd numbered subcarrier have the phases of 45 degrees and minus 45 degrees or 0 degree and 90 degrees. An independent claim is also included for a method for receiving a data packet.
