Method and apparatus of a fully-pipelined layered ldpc decoder


Processors are arranged in a pipeline structure to operate on multiple layers of data, each layer comprising multiple groups of data. An input to a memory is coupled to an output of the last processor in the pipeline, and the memory's output is coupled to an input of the first processor in the pipeline.

N-way doherty distributed power amplifier with power tracking


A power amplifier using n-way doherty structure with adaptive bias supply power tracking for extending the efficiency region over the high peak-to-average power ratio of the multiplexing modulated signals such as wideband code division multiple access and orthogonal frequency division multiplexing is disclosed. In an embodiment, present invention uses a dual-feed distributed structure to an n-way doherty amplifier to improve the isolation between at least one main amplifier and at least one peaking amplifier and, and also to improve both gain and efficiency performance at high output back-off power.
