Abstract
Apparatuses and methods for optimizing rate-distortion costs in a signal are disclosed. An apparatus may comprise a quantization block that may be configured to generate a plurality of candidates for each of a plurality of coefficients. The quantization block may further generate a respective plurality of arcs based, at least in part, on the plurality of candidates. The quantization block may be configured to determine which of the plurality of arcs has a lowest cost using a trellis optimization technique. Fractional bit estimations may be used to calculate rate, and inverse lambda may be used to calculate candidate coefficients.
