Method and system for Gaussian filter modification for improved modulation characteristics in Bluetooth RF transmitters |
摘要 |
Certain aspects of the invention may comprise determining an impulse response of a first Gaussian filter based on a filter length and an oversampling ratio (OSR). The most significant coefficients of the first Gaussian filter may be modified to create a target filter. An upper limit and a lower limit for deviation of the modified most significant coefficients for the target filter may be determined. A magnitude response for the target filter may be constrained based on at least a selected corner frequency, which is related to the OSR. A line search algorithm may be executed on the constrained magnitude response to generate new coefficients for the target filter.
