Patent number: 8664994Abstract: Embodiments of the disclosure relate to an all-digital technique for generating an accurate delay irrespective of the inaccuracies of a controllable delay line. A sub-sampling technique based delay measurement unit capable of measuring delays accurately for the full period range is used as the feedback element to build accurate fractional period delays based on input digital control bits. The delay generation system periodically measures and corrects the error and maintains it at the minimum value without requiring any special calibration phase. A significant improvement in accuracy is obtained for a commercial programmable delay generator chip. The time-precision trade-off feature of the delay measurement unit is utilized to reduce the locking time. Loop dynamics are adjusted to stabilize the delay after the minimum error is achieved, thus avoiding additional jitter.Type: GrantFiled: March 8, 2013Date of Patent: March 4, 2014Assignees: Department of Electronics and Information Technology, Indian Institute of ScienceInventors: Bharadwaj Amrutur, Pratap Kumar Das

Patent number: 8667380Abstract: A transmitter device (110T) for secure communication includes: an encoder (170) configured to apply a non-systematic error correcting code (NS ECC) to a message, thus producing encoded bits with no clear message bits; and a transceiver (720) configured to transmit the encoded bits over a main channel to a receiver. A method for secure communication includes: encoding a message with an NS ECC to produce an encoded message carrying no message bits in the clear; and transmitting the encoded message over a main channel (120). The NS ECC characteristics result in an eavesdropper channel error probability under a security threshold (320) and a main channel error probability over a reliability threshold (310), whenever an eavesdropper (140) listening on an eavesdropper channel (150) is more than distance Z (220) from the transmitter. Unreliable bits in the encoded bits render the eavesdropper unable to reliably decode messages on the main channel.Type: GrantFiled: October 8, 2009Date of Patent: March 4, 2014Assignees: Georgia Tech Research Corporation, Korea Advanced Institute of Science and Technology (KAIST)Inventors: Steven William McLaughlin, Demijan Klinc, Jeongseok Ha
