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.
