摘要: A cross-layer rate adaptation mechanism for wireless local area network (WLAN) can obtain the channel state by calculating the Eb/N0 ratio of ACK frame transmitted from the receiver side. The mechanism determines the transmission rate of the next frame by referring to a predefined reduced mode table. When receiving an ACK frame fails, the mechanism can automatically lower the transmitting rate of the next transmission. Therefore, the method can reduce the damage to the system when ACK frame failure happens.

摘要: A method for preparing an ion source from nanoparticles is provided. The method includes the steps of: providing nanoparticles, vaporizing the nanoparticles from a solid state to a gaseous state, and ionizing the gas to form the ion source. The ion source is prepared by placing solid nanoparticles in a stainless tube, heating and vaporizing the solid nanoparticles into a gaseous state, and ionizing the gas. The gas can be formed at a lower heating temperature than when solid lumps are used because solid nanoparticles have a lower melting point than solid lumps. Thus, the heating temperature is lowered, and the preparing time of the ion source is shortened. Besides, under the same temperature, an ion source prepared from nanoparticles provides higher vapor pressure and allows a higher implantation dose than when the ion source is prepared from solid lumps, thus expanding the applicability of ion implantation technology.
