Abstract
Systems are described that reduce or obviate the impact of limited processing resources and/or limit the power consumption in a receiver having signal processing functions at least partially implemented in software. A wireless receiver includes reception means for receiving a signal over a wireless channel in a wireless external environment. The receiver includes storage means, and a processor configured to perform a plurality of signal processing functions for extracting processed data from said signal, each of said signal processing functions having a plurality of alternative software implementations requiring different levels of usage of a processing resource. The processor estimates at least one parameter relating to the external environment and selects and executes one of the software alternatives for each of the respective signal processing functions to apply a set of implementations adapted to a required quality of said processed data. Related methods and computer program products are described.
