Positioning Using Synthesized Wideband Channel Estimation and Synchronized Receivers

A method for positioning using synthesized wideband channel estimation, comprising:

• capturing, at at least one receiver node, a first received signal of a reference signal from a transmitter at a first carrier frequency;
• performing a reconfiguration to enable signal reception at a second carrier frequency;
• capturing a second received signal of the reference signal from the transmitter at the second carrier frequency;
• continuing to capture subsequent received signals until a plurality of frequencies in a synthetic wideband channel are sufficiently represented in a set of received signals;
• calculating segment channel estimates by performing channel estimation on each of the set of received signals;
• aligning overlapping sections of the calculated segment channel estimates to form a combined channel estimate of the synthetic wideband channel;
• deriving a shortest path delay value from a plurality of delays based on the combined channel estimate;
• deriving a time of arrival for the first received signal from the shortest path delay value;
• and
• estimating a position of the transmitter using the derived time of arrival, thereby using a channel estimate of a synthesized wideband channel to estimate the position of the transmitter.
