Is the Doppler effect a channel?
We offer a pedagogical study of the Doppler effect as a channel, and derive a mathematical model of the input-output relation in both classical and relativistic settings. We then show for the derived channel models the well known result that the classical model is the limit of the relativistic one at low speeds.

What is delay Doppler channel representation?
Delay Doppler channel representation utilizes existing uplink reference signals such as SRS & DMRS, along with periodic DL CQI reports to extract robust geometric information and to compute downlink SINR and predict downlink CSI — even on paired FDD spectrum separated by as much as 400MHz. SRS is a key source for channel information.

How accurate is a delay Doppler channel?
Due to its geometric nature, the slow changing Delay Doppler channel representation opens up the door for functionality disaggregation. Specifically, channel predictions can remain accurate for approximately 50-100 milliseconds (depending on the environment).

What are delay Doppler pulses?
In contrast, in the Delay Doppler representation, one can construct localized pulses which behave as if they are simultaneously localized both in time and in frequency. Such delay-Doppler pulses can be used effectively for Delay Doppler Radar multi-target detection and wireless communication.

What are delay Doppler variables?
In radar theory, the Delay Doppler variables are used to represent and separate moving targets through their delay (range) and Doppler (velocity) characteristics. In communication, the variables represent channels through a superposition of time and frequency shift operations.
