Abstract:

Devices, systems, and method for compensating for non-line-of-sight (“NLOS”) bias in time difference of arrival (“TDOA”) estimates between a first anchor and a second anchor in a network having an obstacle in the line-of-sight therebetween are provided. The systems and methods include transmitting a first packet from a first anchor; indirectly receiving the first packet by a second anchor, then transmitting a second packet by the second anchor; indirectly receiving the second packet by the first anchor; and receiving the first packet and the second packet by a mobile node. The true fly-time of the first or second packets between the first anchor and the second anchor and the bias in time of flight of the first or second packets between the first anchor and the second anchor are estimated. The time difference of arrival at the mobile device between a direct path and an indirect path is further estimated and the NLOS bias in the time difference of arrival estimated at the mobile device is corrected.

International Classification:

H04L 1/00
H04L 7/04

Abstract:

A method of decoding a plurality of diverse signals for low-density parity-check (LDPC) decoders that takes advantage of signal diversity. The method allows for the combining of soft-decision LDPC encoded non-coherently modulated signals, which is in contrast to existing approaches where hard decision combining is used for non-coherently modulated signals. The method includes the steps of inputting each diversity signal into a unique demodulator, and calculating the LLR of each demodulated signal. When the diverse demodulated signals are combined into a single combined signal, each bit of the combined signal is selected according to the value of either the highest LLR value of each bit across the demodulated signals or according to the sum of the LLR of each bit across the demodulated signals.
