Abstract:
1. A transmitting apparatus comprising: a generation unit configured to generate a packet signal including a plurality of CDD (Cyclic Delay Diversity)-applied streams; and a radio unit configured to send the packet signal from a plurality of antennas, wherein the generation unit includes in the packet signal, information permitting a receiving apparatus to perform a smoothing process of channel coefficients across sub-carries when an amount of shift for CDD for the packet signal to be sent from the plurality of antennas becomes smaller than a threshold value defined for time, otherwise prohibiting the receiving apparatus to perform the smoothing process, wherein the generation unit generates a packet signal in which a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signal field L-SIG), a high throughput signal field (HT-SIG), a high throughput short training field (HT-STF), multiple high throughput long training fields (HT-LTF), and data are assigned in the stated order and the information is included in the high throughput short training field (HT-SIG).
