Receive filters to minimize side lobes in a UWB system

摘要

Methods, systems, and devices for maximizing signal to interference plus noise ratio of a channel in a location tracking system. The methods, systems, and device may include tools and techniques for minimizing interference from adjacent samples at a receive filter, may include relaxing constraints at a transmitter. A receive filter or set of receive, or both, filters may be determined and utilized by specifying and or determining various transmitter, receiver, and channel characteristics. The receive filter and set of filters may be determined through an iterative approach involving one or more solution metrics.

1. A method to minimize side lobes at a receive filter, comprising:
identifying transmit filter coefficients at a chip rate; identifying channel characteristics of a channel to determine a number of receive filter taps to obtain a target signal to interference plus noise ratio (SINR); identifying receive filter coefficients at the chip rate, the receive filter coefficients being based at least in part on the determined number of receive filter taps; and applying a solution metric to obtain the receive filter, the solution metric being based at least in part on the identified transmit filter coefficients and the determined number of receive filter taps.
