Abstract

A novel two group bit loading algorithm is proposed for use in a multicode CDMA transmission method at the physical layer in order to improve an adhoc radio system performance. The proposed algorithm provides better data rates than rates achievable with the current HSDPA type of algorithm. The paper also proposes a MAC layer enhancement for use in an adhoc network to improve the total throughput by as much as 10 times by increasing the payload duration for the transmission packets. The throughput increases rapidly for a small packet size and reaches an asymptotic value for large packets.
