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 ...

Adaptive block-equalizers for the UTRA-FDD downlink
IEEE Wireless Communications and Networking Conference, 2005, 2005Novel and simple concepts for adaptive block-equalizers to be used in the downlink of the Universal Mobile Telecommunication System (UMTS) terrestrial radio access (UTRA) with frequency-division duplex (FDD) are presented. The adaptation of the block-equalizers using modified least-squares (LS) or minimum mean-square error (MMSE) schemes is based on ...

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.
