Abstract: The present technique relates to a transmission device, a transmission method, a reception device, a reception method, and a program capable of reducing interference to an adjacent channel in a case where connected-transmission is performed. A transmission device according to an aspect of the present technique includes a signal generating unit configured to generate a plurality of signals having a predetermined frequency bandwidth, a power adjusting unit configured to adjust power of signals so that the power of a signal transmitted using a frequency band close to an end of a channel is less than the power of the signal transmitted using a frequency band close to a center of the channel, and a transmission unit configured to use the channel to transmit, in a connected manner, the signals of which powers have been adjusted. The present technique can be applied to a transmission device for performing connected-transmission.

Abstract: The present technology relates to a reception device, reception method, and program that can prevent erroneous detection of a predetermined signal, such as a P1 signal, included in, for example, a received signal such as DVB-T2.A correlation calculation unit obtains a correlation value between received signals including a predetermined signal in which an original signal and a duplicate signal obtained from a copy of at least a part of the original signal are disposed. An average power calculation unit obtains average power of the received signals. A normalization unit obtains a normalized correlation value obtained by normalizing the correlation value by the average power. The present technology can be applied to a case where a P1 signal being a preamble signal is detected from a received signal such as DVB-T2, for example.
