The present invention provides a syringe cartridge that is sufficiently robust to be used in autoinjectors that generate injection forces sufficient to deliver viscous medicaments. A dedicated subchannel interferes with only one adjacent dedicated subchannel, even with a large synchronization error, by permutating the dedicated subchannels by cyclic shifts, whereby diversity gain can be maintained and interference between adjacent channels can be minimized. These aspects are implemented as an apparatus, a method, computer readable medium, and a data structure. The multi-predictor makes predictions about future workload characteristic by periodically reading available hardware counters.
