Effects of variation in computational latency can be controlled by using a processor to perform computations associated with a signal processing process, each computation related to processing an input sample to generate an output, and allocating a processing cost per computation that is less than a maximum processing cost of the processor for performing any one of the computations and greater than an average processing cost of the processor for performing the computations. The allocated processing cost for a computation is an allocated time period between receipt of the input sample and generation of the output for the computation. A task requiring a processing time greater than the allocated processing cost is handled as a source of jitter in the signal processing process.

Controlling jittering effects

Transmitting messages to mobile telephones includes determining a time a standard requires or permits a standard compliant transmission to be received by a user, and scheduling a transmission by a base station to the user in the future based on a distance between the user and a base station such that the transmission will be received by the user at the determined time. The distance between the user and the base station is a distance such that a propagation delay between the user and the base station is larger than a propagation delay accommodated by the standard.
