高空平台-地面CDMA系统上行容量提高

Abstract

Abstract:

According to the characteristic that the inter-cell interference factor of the HAPS CDMA system is lower than that of the terrestrial CDMA system, the disadvantage of the ring structure is pointed out and an improved multi-layer structure is proposed in which two adjacent terrestrial layers are seperated by several HAPS layers. The uplink capacity formula for the HAPS-terrestrial CDMA system is deduced and the capacity of the ring structure and that of the multi-layer structure are compared. Numerical results show that the uplink capacity of the HAPS system and that of the terrestrial system of the multi-layer structure increase to 111.9 and 110.2 respectively for a 10-tier system, while the uplink capacity of HAPS system and that of the terrestrial system of the ring structure are only 97.4 and 97.6 under the same condition.

Key words: HAPS, capacity, interference
