Abstract
In a CDMA transmission, a quality of each symbol of a frame is held constant by interleaving spread chip, while overhead and interference amounts in other cells are reduced by easing a rate of transmission power control. Further, transmission power is decreased by discontinuing transmission at the time the quality is satisfied, thereby increasing the system capacity. Furthermore, it is possible to achieve more remarkable effect by performing inverse transmission power control.
