The present disclosure relates to a communication device and a communication method that enable adaptive positioning. A communication unit performs wireless communication with a peripheral communication apparatus, and a processing unit outputs, on the basis of a frequency characteristic of a propagation channel, information of a distance to the communication apparatus and reliability level information representing a reliability level of the distance information. The present disclosure can be applied to, for example, a BLE chip.

Communication device and communication method

Provided are a distance measurement device and a distance measurement method for accurately measuring a distance even when multipath occurs. The present technology provides a distance measurement device including a first transceiver, a second transceiver, a response information acquisition section, a filter, and a distance calculator. The first transceiver transmits a first pulse signal to the second transceiver while performing frequency sweeping. The second transceiver receives the first pulse signal transmitted from the first transceiver. The response information acquisition section acquires response information on a basis of a phase difference obtained by reception of the first pulse signal. The filter extracts initial response information from the response information, the initial response information being the response information related to the first pulse signal to be received at an initial stage. The distance calculator calculates group delay on a basis of the initial response information, and calculates a distance between the first transceiver and the second transceiver by multiplying the group delay by a light velocity.
