SYSTEMS, METHODS, APPARATUS, AND COMPUTER-READABLE MEDIA FOR DYNAMIC BIT ALLOCATION

A dynamic bit allocation operation determines a bit allocation for each of a plurality of vectors, based on a corresponding plurality of gain factors, and compares each allocation to a threshold value that is based on a dimensionality of the vector. There is described a method of bit allocation, said method comprising: for each among a plurality of vectors, calculating a corresponding one of a plurality of gain factors; for each among the plurality of vectors, calculating a corresponding bit allocation that is based on the gain factor; for at least one among the plurality of vectors, determining that the corresponding bit allocation is not greater than a minimum allocation value; and, in response to said determining, for each of said at least one vector, changing the corresponding bit allocation.
