Abstract:
A device and a method for processing CDMA compliant signals. The method includes receiving input signals; selecting, for each time interval out of multiple evenly length successive time intervals, multiple selected channel processing tasks that are scheduled to be at least partially executed during the time interval; storing input data at a first input buffer and providing data associated with at least one selected processing task from a second input buffer during even time intervals; and storing input data at the second input buffer and providing data associated with at least one selected processing task from the first input buffer during odd time intervals.

Abstract:
A mobile radio (10) with a synchronization apparatus (14) executes a method (60) for time synchronizing the radio (10) and a base station (12). Base station (12) and radio (10) have internal timers (26, 16). A control unit (18) in the radio (10) receives a signal (29) from the base station (12) and determines the difference F between timers (26, 16, 30) in the base (12) and mobile (10). The control unit (18) writes instructions I(i) and their execution times T(i) to a memory (42) within the radio (10). One of these instructions I(N) reloads the radio timing counter (30) with a corrected value C=f(F,B) at a predetermined time T(N)=B which avoids conflicts with other operations of the radio (10).
Abstract:
A radio (10) executes a method (100) for entering and exiting a halt status. Radio (10) has a control unit (18) and an internal timing unit (16). The timing unit (16) has execution logic (32), a status register (46) a counter (30) and a clock source (37). The control unit (18) writes instructions I(i) and their execution times T(i) to a memory (42) within the execution logic (32). One of these instructions is a ‘SWITCH CLOCK’ instruction causing the timing unit (16) to switch between clock signals. One of the instructions is ‘HALT COUNTER’ causing the radio (10) to enter a halt state. The radio (10) can be synchronized to the end of a first communication frame received by it after exiting a halt state.
