UTRA/FDD RF Transceiver Requirements
Wireless Personal Communications, 2002Unified RF requirements are derived for an UMTS Terrestrial Radio Access/Frequency Division Duplex (UTRA/FDD) compliant mobile transceiver. A set of transceiver requirements are proposed with consideration to system issues including duplex aspects. From these design-compatible requirements are proposed for each functional block in the transceiver.

Performance of a WCDMA FDD Cellular Multihop Network
2005 IEEE 16th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006Cellular multihop networks have the potential to decrease power consumption, increase coverage and/or enable higher data rates. We propose using in-band transmissions for the connection between a fixed repeating device and the cellular base station. A user connected via the repeater use one frequency band (fq2) for the communication to the repeater and

Space-time combining in the uplink of UTRA/FDD
Globecom '00 - IEEE. Global Telecommunications Conference. Conference Record (Cat. No.00CH37137), 2002We investigate various array combining algorithms considering the special requirements of the UTRA/FDD uplink. After formulating the algorithms, we assess their performance in a modified vehicular B channel that is spatially inhomogeneous. The bit error ratios in different situations are presented together with some considerations about the ...

In telecommunication, there are various ways to communicate between two points, referred to as mode of operation. This is usually done in three ways: simplex, half-duplex, and full duplex. Simplex is a one-way communication such as broadcasting. Half duplex is a two-way communication but one at a time such as taxi dispatch system.
