A mobile in soft handoff maintains simultaneous radio links with multiple base-stations which enables it to make use of the best quality leg most of the time. We present an analysis of fade margins for systems allowing soft handoffs e.

In cellular communications, the handoff is the process of transferring an active call or data session from one cell in a cellular network or from one channel to another. In satellite communications, it is the process of transferring control from one earth station to another. Handoff is necessary for preventing loss of interruption of service to a caller or a data session user. Handoff is also called handover. If a subscriber who is in a call or a data session moves out of coverage of one cell and enters coverage area of another cell, a handoff is triggered for a continuum of service. The tasks that were being performed by the first cell are delineating to the latter cell. Each cell has a pre-defined capacity, i.

Soft handoffs in CDMA mobile systems Abstract: This article presents an overview of soft handoff, an idea which is becoming quite important because of its use in the IS code-division multiple access CDMA cellular phone standard. The benefits and disadvantages of using soft handoff over hard handoff are discussed, with most results drawn from the available literature. The two most well-known benefits are fade margin improvement and higher uplink capacity, while disadvantages include increased downlink interference and more complex implementation.

The present invention relates to a kind of medium-soft changing method and system that uses a plurality of common frequencies, relate in particular to a kind of system and method that in the mobile communication system that adopts code division multiple access CDMA , switches distribution inter-cell inter-frequency assignments between the frequency of execution minizone with medium-soft. When radio telephone travelling carriage or unit moved to various zone, the communications transmit difficulty should be minimized, and when travelling carriage was idle, travelling carriage must be set up new registration procedure frequently according to various parameters. In calling procedure, the communication between travelling carriage, base station and board management travelling carriage and the base station is to keep acceptable radio link efficient. Thereby CDMA and wideband CDMA system can be handled from a base station to another base station in a base station or the switching from an antenna area to another zone. For successional reliability and system load about the calling that drawn by changing method and content, these various multi-form switchings have different efficient.

Wireless Information Networks pp Cite as. This paper presents an analysis of soft handoff and its effect on the coverage area of a CDMA system. We obtain the probability of service at the edge of the cell and hence the area reliability of the CDMA system. We also examine the dependence of the service probability and the area reliability on the soft handoff area and the required fade margin. A CDMA network planning tool based on the soft handoff analyses has been used to calculate the average outage probability area reliability on a site-by-site basis.

Формула Цифровой крепости зашифрована с помощью Цифровой крепости. Танкадо предложил бесценный математический метод, но зашифровал. Зашифровал, используя этот самый метод. - Сейф Бигглмана, - протянула Сьюзан.

Ненависть в его сердце уступила место преданности Будде. Еще через четыре месяца Энсей Танкадо приступил к работе в Отделении криптографии Агентства национальной безопасности США. Несмотря на солидный заработок, Танкадо ездил на службу на стареньком мопеде и обедал в одиночестве за своим рабочим столом, вместо того чтобы вместе с сослуживцами поглощать котлеты из телятины и луковый суп с картофелем - фирменные блюда местной столовой. Энсей пользовался всеобщим уважением, работал творчески, с блеском, что дано немногим.

Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах.
