A 90 nm CMOS 10 GHz beam forming transmitter

A 10 GHz beam forming transmitter was designed in a 90 nm CMOS process. Two power amplifiers with independently controllable phase enable the beam forming. The controllable phase is accomplished by switching in binary weighted transistors fed by quadrature signals, which are generated by a quadrature voltage controlled oscillator followed by a buffer. The design contains seven differential on-chip

Population dynamics and demography - inferences from stochastic models

Time series analysis of population abundances is a common approach to making inferences about population dynamics, and especially for estimating density dependence. Traditionally the impact of potential errors in observations or measurements of the abundances on inference has been ignored. Following the increased availability of appropriate software as well as statistical awareness among ecologist

Strukturmekanik - Modellering och analys av ramar och fackverk

Strukturmekanik är den del av fysiken som beskriver hur olika material, som formats och sammanfogats till strukturer, bär sina laster. Kunskapen om dessa strukturers verkningssätt kan användas i en skapande process där hållbara och effektiva, funktionella och uttrycksfulla byggnadsverk utformas. Den här läroboken i strukturmekanik baseras på finita elementmetodens metodik. Förståelsen för struktu

Improving Code Diversity on Block-Fading Channels by Spatial Coupling

Spatially coupled low-density parity-check (SC-LDPC) codes are considered for transmission over the block-fading channel. The diversity order of the SC-LDPC codes is studied using density evolution and simulation results. We demonstrate that the diversity order of the code can be increased, without lowering the code rate, by simply increasing the coupling parameter (memory) of a SC-LDPC code. For
