Abstract
A method and apparatus are disclosed for use with multiple input, multiple output (MIMO) signal processing techniques, which reduce the amount of memory and memory bandwidth used to store and access filter coefficients by compressing a filter coefficient based at least in part on one or more neighboring filter coefficients for storage and decompressing the filter coefficients when retrieved. The decompressed filter coefficients can be used with a MIMO filtering technique, and/or can be used to compress or decompress additional coefficients.
