Problems solved by technology

More generally, a processor could in principle perform several different operations, with the consequence that managing processing resources would become a significant problem
[0010] In addition, many computer processors are limited in their ability to efficiently handle different types of data processing calculations with certain algorithms and in their ability to execute different algorithms by having a limited instruction set that is fixed at the time of manufacture

Embodiment Construction

[0032] figure 1 is a schematic block diagram of an apparatus for transmitting and receiving signals in a wireless communication system. Such a device can be implemented in a number of different ways, but depending on the figure 1 A series of radio RF / IF stages are arranged to receive and transmit radio signals (TX, RX) via one or more antennas 20 . The signal received at the output of the RF / IF stage is usually converted to baseband, where an analog-to-digital converter (ADC) converts the analog signal into digital samples. figure 1 Block 32 of λ comprises means for processing the received radio signal and providing digital samples r(k). This can be achieved in different ways, which are known in the art and will not be discussed further here.

[0033] The processor 100 includes a processor platform 101 , a data memory 104 and an instruction memory 102 . The sample r(k) is supplied to a data delivery engine 30 which communicates with the processor platform 101 , instruction...

Abstract

One aspect provides a method of processing a signal transmitted over a channel in a wireless communication system. In one embodiment, the method comprises receiving at a receiver the signal transmitted over the channel, estimating at intervals at least one parameter of a time varying communication environment of the system, monitoring at least one processor-related criterion of a processor at the receiver, and selecting a signal processing function from a plurality of signal processing functions implementable by the processor. The selecting of the signal processing function is based on both the at least one parameter and the at least one processor-related criterion. Each signal processing function comprises a plurality of code blocks which process the received signal. Each code block of the plurality of code blocks comprises a sequence of instructions for execution by on a processor platform of the processor.

Description

technical field [0001] The invention relates to processing radio signals in a wireless communication system. Background technique [0002] The transmission of data-carrying radio signals in modern wireless communications can be carried out based on a number of different communication systems, usually specified by standards. There is an increasing need for devices that are operable to support more than one of these wireless communication systems. A mobile radio receiver device includes an analog radio frequency (RF) / intermediate frequency (IF) stage arranged to receive and transmit wireless signals via one or more antennas. The output of the RF / IF stage is typically converted to baseband, where an analog-to-digital converter (ADC) converts the incoming analog signal into digital samples, which are then processed for signal detection and decoded in the form of a reliability value the data. The ADC may alternatively operate directly at the IF, in which case the conversion to...
