SUPER-REGENERATIVE TRANSCEIVER WITH IMPROVED FREQUENCY DISCRIMINATION
The present disclosure provides a super-regenerative transceiver with a feedback element having a controllable gain. The super-regenerative transceiver utilizes the controllable gain to improve RF signal data sensitivity and improve RF signal data capture rates. Super-regenerative transceivers described herein permit signal data capture over a broad range of frequencies and for a range of communication protocols. Super-regenerative transceivers described herein are tunable, consume very little power for operation and maintenance, and permit long term operation even when powered by very small power sources (e.g., coin batteries).

Timing estimation device and timing estimation method
A timing estimation device according to the present invention includes a received signal memory that outputs a plurality of sample groups each of which is a first number of samples extracted at symbol rate intervals from an oversampled received signal containing a known sequence, with shifting their leading positions by one sample from each other, a reliability calculation unit that calculates a channel impulse response for each of the sample groups, based on the sample group, generates a replica of the received signal using the channel impulse response and the known sequence, and calculates a reliability value based on the sample group, the replica, and the channel impulse response, and a timing estimation unit that estimates a preceding wave arrival timing and a delayed wave arrival timing, based on the reliability value.
