Interference canceling CDMA mobile station receiver

An apparatus for adaptively allocating computational resources in real time processing of a communications signal, the apparatus comprising:

• means for receiving a stream of data corresponding to a communication signal;
• means for ensuring a completion of a time-critical process for the received stream of data, the time-critical process including a demodulation of the communications signal;
• means for adaptively applying a non-time-critical process to the received stream of data, the non-time-critical process including an interference cancellation from the received stream of data and being applied to the extent that computational resources become available subject to ensuring the completion of the time-critical process;
• and
• means for loading a first buffer with a first block from the stream of data, and a second buffer with a second block from the stream of data, wherein the means for ensuring the completion of the time-critical process ensures the completion of the time-critical process for the block in the first buffer prior to receiving an indication that a third buffer has been filled with a third block of data from the stream of data.

A receiver that adaptively allocates computational resources in real time processing of a communications signal, the receiver comprising:

• an input, which receives a stream of data corresponding to a communication signal;
• a time-critical processing module, which ensures a completion of a time-critical process for the received stream of data, the time-critical process including a demodulation of the communications signal;
• a non-time-critical processing module, in operative communication with the time-critical processing module, which adaptively applies a non-time-critical process to the received stream of data, the non-time-critical process including an interference cancellation from the received stream of data and being applied to the extent that computational resources become available subject to ensuring the completion of the time-critical process;
• and
• a buffer loading module, which loads a first buffer with a first block from the stream of data, and a second buffer with a second block from the stream of data, wherein the time-critical processing module ensures the completion of the time-critical process for the block in the first buffer prior to receiving an indication that a third buffer has been filled with a third block of data from the stream of data.
