Abstract

Methods and structures are described for processing signals formatted according to a plurality of different wireless and broadband standards. In some embodiments, network resources are shared to enable energy efficient, pseudo-simultaneous processing. In some embodiments, a timestamp is prepended to input data to remove jitter associated with time division multiplexed processing using shared resources. Systems according to embodiments of the invention are also disclosed.
