A filter unit determines a mapping of range combinations to filters. Each range combination includes a range for a first metric and a range for a second metric. The filter unit determines a unique range combination identification (ID) for each range combination, with each unique range combination ID corresponding to a sequential value. The filter unit assigns a unique group ID to each group of range combinations. A group of range combinations includes range combinations mapped to the same filter, and the unique group IDs correspond to a set of sequential values. The filter unit signals or reconstructs coefficients for the filters in an order based on the sequential values of the group IDs. |
