Wideband CDMA,complex spread signals is also included, which illustrates that the complex spread signal has more stable envelope than the dual-channel spread signal. The power ratio of pilot to data channels should be chosen in the range of 0.2 to 0.4 (?7 dB to ?4 dB) in order to achieve maximum system capacity.作者: 創(chuàng)作 時(shí)間: 2025-3-23 07:50

Open-loop Power Control in CDMA Overlay,power control error in the presence of narrowband interference are analyzed and numerically computed. In order to get a minimum power control error in the CDMA overlay situations, an optimum downlink power allocation scheme is used, which works well for wide range of signal to narrowband interference ratio.作者: META 時(shí)間: 2025-3-25 11:00 作者: 創(chuàng)造性 時(shí)間: 2025-3-25 14:29
