Abstract: Method for variable arbitrary resampling that allows a base station test system to correct for sampling frequency errors relative to the base station. An output time calculation module obtains the required output sample times depending on the resampling rate, which can be tuned as needed. An input sample counter module counts the last input sample loaded into a polyphase interpolator, which can calculate any of M interpolated samples between two consecutive input samples. The polyphase interpolator uses the integer part of the required output sample times to decide what interpolated samples to calculate. A sequencer module compares the calculated output times against the input sample count to control all the blocks of the variable arbitrary resampler and determine if the output of the polyphase interpolator is a valid sample. Valid samples are transferred to other subsystems, such as a digital-to-analog data converter or another signal processing module.

Abstract: The disclosure details the implementation of an apparatus, method, and system for a macroeconomic equity investment design and trade system (the Wavefront system). The disclosure teaches a set of quantitative tools to help investors design trades around macro themes. Part of the approach is a linked set of models called Wavefronts, which describe how economic shocks ripple through the economy into company performance, market value and equity returns in the US market. In one embodiment, the modeling may be viewed as having in three parts. The first converts an economic shock into a comprehensive set of shifts in the economy. The second takes those economic shifts and drives them into company fundamentals. The third values those fundamentals based on what the market normally pays.
