⎯ This paper describes the performance evaluation of fixed step closed loop power control algorithm in a novel wireless channel that is called High Altitude Platforms (HAPs). This new wireless delivery method is proposed as a complementary system in providing the next generation services in which the technology basically employs CDMA. In HAPs communication,(More)
—The implementation of complex signal processing algorithms are required to achieve robust transmission, whereas mobile wireless application require low power dissipation. This paper describes an algorithm and a corresponding hardware architecture for the implementation of OFDMA 802.16e channel estimation. The advantage of the proposed architecture are low(More)
In the future, wireless broadband communication systems will not only be used for private access, but also public access with high data rate. The problems in transmitting high data rate at high speed mobility are how to provide wide bandwidth in rapidly changing channel condition, to mitigate selective fading problems, to estimate response of the channel,(More)
