Improved strategy of time-frequency opportunistic spectral usage for multi-rate wireless systems

Abstract

In this paper, we present an improved strategy of channel probing and transmission scheduling in a multi-rate wireless system. We consider a fixed data time model, where time is slotted and channel states do not change within one slot. In a multichannel wireless system, a transmitter can opportunistically use channels with high-quality conditions. In order… (More)
