Abstract
Methods, systems, and devices for channel estimation in a location tracking system are described. The methods, system, and devices may include tools and techniques for determining and/or designing perfect or semi-perfect sequences (including preamble sequences) for implementation in a location tracking system. Sequences having 2's exponent dimensionality, such as ternary sequences, may be determined and employed, which may help reduce implementation complexity and/or operating power consumption. Sequences may be determined using mean square error and/or maximum autocorrelation peak performance metrics.
