Many previous works focus on subcarrier allocation problems in OFDM-based ISAC. However, did not consider when OFDM subcarrier is insufficient, which means sensing and communication have to be reused ...
We introduce SubScatter, the first subcarrier-level frequency-modulated OFDM backscatter which is able to tolerate bigger synchronization errors, STO, and CFO. The unique feature of SubScatter is our ...
OFDM stands for orthogonal frequency division multiplexing, which is a method of transmitting data over multiple subcarriers in a single channel. Each subcarrier is modulated with a different part ...
Abstract: An adaptive channel estimation algorithm for the channel length is proposed to construct a channel estimation model suitable for orthogonal frequency division multiplexing (OFDM) underwater ...
