系统容量 ：在保证通信质量的前提下，功率控制算法能够支持的用户数量和数据传输速率。
There isn't any soft handover and consequently pico-cells overlap in very same building and may generate self interference
The 3rd way would be to ‘Search our systems’ via a key phrase lookup. This Web content is intended to deliver an overview of the hot subjects and new characteristics coming up.
With CDMA, alerts that aren't correlated with the channel of fascination (which include other PN offsets from adjacent cellular foundation stations) look as noise, and indicators carried on other Walsh codes (which might be appropriately time aligned) are in essence taken out while in the de-spreading course of action.
The Get the job done Plan is usually a table that contains all the deliverables currently being labored on, with the most recent WIDs and SIDs at the best in the program and before objects mentioned at the bottom.
A generalized RAKE receiver for interference suppression and multipath mitigation is proposed, exploiting The point that time dispersion drastically distorts the interference spectrum from Each and every base station during the downlink of the wideband CDMA process.
To prepare for the long run, organizations ought to put money into check here Superior multi-copyright shipping methods, keep updated with industry tendencies, and continually evaluate and strengthen their shipping strategies.
The HSDPA will result in 3G network to run on bigger load rate everytime.So this improves sound on current UMTS and after that decreases UMTS capacity.
Whenever you click on a backlink to Wikipedia, Wiktionary or Wikiquote in the browser's search engine results, it will eventually show the modern read more Wikiwand interface.
It truly is well worth noting that whilst EVDO experienced various applications, its importance diminished over time as 4G LTE and 5G networks available more rapidly speeds and much more Sophisticated abilities, rendering EVDO out of date in many areas.
保密通信 ：扩频信号在频域上与噪声无异，增加了信号截获的难度，增强了通信的保密性。
3G, the leading supplier of transportation and delivery management software, proudly adds drayage services to the 3G Transportation Suite. Examine more. Link with industry gurus and friends at functions, in which you’ll get the understanding and insights needed to lead in logistics
These interrupt levels are also called the edge-triggered interrupt where by the masking course of action is connected to the individual interrupt bits with sixty four pins.
Originating in the late nineties and early 2000s, read more EVDO enhanced the abilities of the present CDMA2000 technology, a combination of 2G and 3G standards, concentrating specifically on optimizing data throughput.
