  • In this paper a coverage scheme consisting of both fixed and configurable beams is proposed for HAPS WCDMA systems. According to different user distribution, the system capacity is optimized by embedding configurable beams in fixed beams rationally and adjusting the position and size of them efficiently. The numerical results show that a higher and more stable system capacity is expectable despite variation of user distribution, and large number of beams are also economized. This good performance especially appears in solving the problem of the hot spot in communication.
