Abstract :
We investigate and evaluate the performance of two scheduling algorithms for forward link packet access: in CDMA based cellular networks. Both algorithms use round-robin scheduling, ensuring fair access to users in overlapping and non-overlapping areas. One method provides time diversity whereas the other provides time as well as space diversity to users located in the handoff regions. The performance is also compared with that of a conventional hard handoff
