Patent ID: 6888851

Claim:
A method for decreasing the size of a frame of digital data from a first number of bits to a second number of bits, the method comprising: (a) Receiving a frame having LM bits ordered from a first bit to an LMth bit; and (b) Deleting LMâˆ’N bits from the frame in a single iteration through the data, thereby creating a reduced length frame of length N for processing in a digital communications system, wherein the deleting step is performed such that the distance between any two consecutive deleted bits within any group within a first subset of the frame is A bits, and the distance between any two consecutive deleted bits within any group within a second subset of the frame is B bits, where A is an integer greater than 0 and B is an integer greater than A, and where the first subset and the second subset together form a first plurality of consecutive bits.
