Comparison of wireless Access Technologies (WCDMA, HSPA, HSPA+, LTE)

WCDMA, HSPA, HSPA+, LTE

"An information system formed by HAP (High Altitude Platform) will be a new generation-system for the wireless communications and HAPS (HAP Station) communication system combines the advantages of both terrestrial and satellite communication systems and avoids, to different extents, their disadvantages. Third generation (3G) mobile technology which is specified by the third generation partnership project (3 GPP) is definitely one of the candidates. With the success of wireless network, the IEEE 802.16 standard, with its wireless metropolitan area network (MAN) air interface appears to be a strong competitor. We provide initial practical comparison of these two technologies for HAPS Communication".

Multiplexing and Multiple Access

Multiplexing And Multiple Access : Digital Communications Difference between Multiplexing and Multiple Access: Sr.No. Multiplexing Multiple Access 1 “In telecommunications and computer networks, multiplexing is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.” “In telecommunications and computer networks, a channel access method or multiple access method allows several terminals connected to the same multipoint physical medium to transmit over it and to share its capacity.” 2 The multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. A channel-access scheme is based on a multiplex method that allows several data streams or signals to share the...

Difference in between Time division multiplexing (TDM) and Frequency division multiplexing (FDM)

Difference in between TDM and FDM: This page on FDM versus TDM describes difference between FDM and TDM multiplexing . FDM is the short form of frequency division multiplexing and TDM is the short form of time division multiplexing. In FDM each signal is modulated onto different unique RF carrier frequency and all carrier frequencies are separated significantly so that bandwidth of the signals do not overlap in frequency domain. Figure: Difference in between TDM and FDM
