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.

Efficient multiple input multiple output signal processing method and apparatus

A system and method is presented for enciphering information using the Advanced Encryption Standard (AES) algorithm in which a subprocessor is configured to manipulate data as it is being loaded into the subprocessor memory. Thus, unlike implementations in the prior art, which require complete loading of data into a subsystem memory before data manipulation thereby creating a potential bottleneck in memory, this invention reduces the potential bottleneck in memory.
