Abstract:
The present technology relates to a transmission device, a transmission method, a reception device, a reception method, and a program that can improve reception performance of a frame to which a preamble is added. A transmission device of one aspect of the present technology generates a preamble including a sequence [d d . . . d −d] having iteration of a sequence d that is one of sequences a and b that are Golay complementary sequences, followed by an inverted sequence of the sequence d, and including a signal sequence in which a maximum value of an absolute value of a side lobe level of cross correlation between a sequence [d d −d] and a sequence [d −d] is 25 or less. The generated preamble is added to data to be transmitted in units of frames. The present technology can be applied to a device that transmits and receives data via a wireless transmission path.

Claim (Index 12):
A transmission method comprising the steps of:\n generating a preamble including a combination of sequences a and b that are Golay complementary sequences and sequences \u2212a and \u2212b that are inverted sequences of the sequences a and b, and including, in a channel estimation sequence, a signal sequence of any of\n a first basic sequence [a b a \u2212b a b \u2212a b], \n a second basic sequence [a b \u2212a b a b a \u2212b], \n a third basic sequence [a \u2212b a b a \u2212b \u2212a \u2212b], \n a fourth basic sequence [a \u2212b \u2212a \u2212b a \u2212b a b], \n inverted sequences of the first to fourth basic sequences, \n reverse sequences of the first to fourth basic sequences, and \n reverse sequences of the inverted sequences of the first to fourth basic sequences; and \n transmitting data to be transmitted in units of frames to which the preamble is added.
