SYSTEMS, METHODS, AND COMPUTER READABLE MEDIA FOR DIGITAL RADIO BROADCAST RECEIVER MEMORY AND POWER REDUCTION

摘要

A method of block deinterleaving data received at a digital radio broadcast receiver is described. The method includes providing a block of memory having n x k addresses, wherein the block comprises a single table, receiving a digital radio broadcast signal at the receiver, and demodulating the digital radio broadcast signal into a plurality of interleaved data units. For at least one series of n x k data units a pointer step size is determined, and for each data unit in the series, an address in the block is calculated based on the pointer step size, and an output data unit is read from the block at the address, such that said output data units represent block deinterieaved data units. An input data unit from the plurality of interleaved data units is then written to the block at the address. Associated systems and computer readable storage media are presented.
