Agile software teams' frequent releases and fast iterations present a growing need for rigorous user experience research methods that are faster, lighter-weight, and more flexible. To this end, we developed the Informal Cognitive Walkthrough (ICW). This agile research methodology grew organically, over the course of three years, while working with a very(More)
This paper considers field programmable gate array (FPGA) implementations for blind adaptive decision feedback equalizer (DFE) based on the IP core reported in [1]. The design can achieve channel equalization for 16-QAM and 64-QAM. Constant modulus algorithm (CMA) and multi-modulus algorithm (MMA) are considered for update the coefficients in the blind mode(More)
