Fine timing for high throughput packets
View Patent ↗Improved methods of decoding data symbols of a high throughput (HT) data field in a mixed mode packet are provided. In one embodiment, first and second data symbols of the HT data field can be decoded using timing information derived from a legacy header of the mixed mode packet. In another embodiment, the first data symbol of the HT data field can be decoded using timing information derived from a legacy header of the mixed mode packet, whereas the second data symbol of the HT data field can be decoded using approximately half of the tones of the HT long training field in the mixed mode packet. Subsequent data symbols of the HT data field can be decoded using all tones of the HT long training field in the received mixed mode packet.
1. A method of decoding data symbols of a high throughput (HT) data field in a mixed mode packet, the method comprising:
decoding a first data symbol and a second data symbol of the HT data field using timing information derived solely from a legacy header of the mixed mode packet; and
decoding subsequent data symbols of the HT data field using fine timing information derived from an HT long training field in the mixed mode packet.
2. A method of decoding data symbols of a high throughput (HT) data field in a received mixed mode packet, the method comprising:
decoding a first data symbol of the HT data field using timing information derived from a legacy header of the mixed mode packet;
decoding a second data symbol of the HT data field using approximately half of a plurality of tones of an HT long training field in the mixed mode packet; and
decoding subsequent data symbols of the HT data field using all of the plurality of tones of the HT long training field in the received mixed mode packet.
