A method and system for combining signals in a receiver employing antenna diversity. If the interference exceeds a predetermined threshold, interference rejection combining (IRC) is used. If the interference does not exceed the predetermined threshold, maximum ratio combining (MRC) is used. The diversity combining technique can be selected, and the signals combined every burst, half-burst, or other suitable interval.

Selective diversity combining

A method and apparatus for processing interrupts received by a processor during the processing of an instruction set by a processing pipeline is disclosed. Initially, an interrupt associated with an interrupt service routine is received during processing of the instruction set. In response to receipt of the interrupt, an interrupt instruction register is accessed containing at least one interrupt instruction associated with the interrupt service routine. The at least one interrupt instruction is inserted directly into the processing pipeline of the processor. The inserted instruction is then executed and control returns back to processing of the original instruction set after execution of at least one interrupt instruction.
