This paper describes a VLSI implementation of V-BLAST detection for future multiple-input-multiple-output (MIMO) wireless communications. This design is implemented using a 0.35-μm 5-layer metal 3.3 V CMOS technology. For a 4-transmit and 4-receive antennas system using QPSK modulation scheme, a detecting throughput of 128 Mb/s can be achieved. Furthermore, it is shown that the implementation comp

Popular Abstract in Swedish Tensider är en mycket vanlig typ av kemikalier som använts i tusen år och som man ofta stöter på i vardagliga livet. De ingår i exempelvis rengöringsmedel, diskmedel, tvättmedel, lim, målarfärger, hudkrämer och schampo. Tensider är ytaktiva ämnen som anrikas på ytor där de reducerar ytspänningen och därmed ändrar ytans egenskaper. En tensidmolekyl består av en hydrofil A thorough physical-chemical characterisation of alkylglycosides has been performed. The effects of temperature, salt, concentration and deuterium exchange on the self-aggregation of n-nonyl-b-D-glucoside (b-C9G1) and n-tetradecyl-b-D-maltoside (b-C14G2) have been studied in dilute solutions by static and dynamic light scattering, neutron scattering, rheology, capillary viscometry and tensiometry.

Do certain humans and animals have greater value than other humans and animals? The question will be discussed using some examples from pre-Christian burial practices and other depositions of human and animal bones in Scandinavia. During the pre-Christian period it seems that certain humans and certain animals were buried in graves made for the purpose, while other humans and animals were deposite

In Russia, as the confrontation over the constitutional distribution of authority raged, Boris Yeltsin's economic program regularly wended its way in and out of the Constitutional Court until Yeltsin finally suspended that court in the aftermath of his clash with the hard-line parliament. In Europe, French and German legislators and executives now routinely alter desired policies in response to or

Denna framställnings syfte är, att med stöd av existerande kunskap söka efter ej undersökta sociala och psykologiska effekter av att bygga behovssammansatta förband över nationsgränser med interoperabilitet (IO) som mål. Detta tänks ske samtidigt som ett nätverksbaserat försvar (NBF) implementeras inom FM. Förbanden förutsätts vidare vara avsedda för strid i främmande miljöer.

Creation and adoption of corporate policies requires significant commitment of scarce senior management resources. In the absence of processes and tools, convergence upon final policy and may not be achieved in a timely manner. Significant similarities between policy and requirements documents suggest that requirements engineering techniques could be used to generate policy. However, neither evide

The grocery retail industry, with its large product volumes, low margins and fierce competition, is constantly seeking efficiency improvements in its supply chain. The grocery retail industry uses an immense amount of packaging and is directly affected by packaging logistics activities. There is, therefore, a potential for efficiency improvements in the grocery retail supply chain through the inte

The development of real-time ultrasound in the 1970's made indelible inpact on antenatal care. Assessing foetal growth and detecting deviations from normal in both growth and foetal anatomy became fesible. Expectant parents could also 'see' their foetus. Normal foetal growth parameters at term were consituted and selected parameters from the second trimester were evaluated in the detection of chro
