  1. 1. Perceptual Alignment of Retail Brand Image in Corporate Branding: A study of employee perceived stakeholder alignment and effects on brand equity

    Author : Kaj-Dac Tam; Företagsekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perceptual alignment; retailing; corporate branding; retail brand image; brand equity; brand performance;

    Abstract : The term perceptual alignment is used in various research fields to describe the extent to which individuals share the same perceptions about an object or idea. Perceptual alignment is important from a corporate branding perspective because strong corporate brands express associations and sources of ideals that are attractive and appealing to the stakeholders related to the organisation.

  2. 2. On High-Speed Digital-to-Analog Converters and Semi-Digital FIR Filters

    Author : Mohammad Reza Sadeghifar; J Jacob Wikner; Robert Hägglund; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; RFDAC; SDFIR; FIR; semi-digital FIR filter; digital-to-analog converter; D A converter; data converter; mixed-signal integrated circuits; mixer DAC; IQ modulator; transmitter;

    Abstract : High-speed and high-resolution digital-to-analog converters (DACs) are vital components in all telecommunication systems. Radio-frequency digital-to-analog converter (RFDAC) provides high-speed and high-resolution conversion from digital domain to an analog signal. RFDACs can be employed in direct-conversion radio transmitter architectures. READ MORE

  3. 3. Studies on Selected Topics in Radio Frequency Digital-to-Analog Converters

    Author : Mohammad Reza Sadeghifar; Jacob Wikner; Adam Strak; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; Telecommunication; Semi-digital FIR filter; RF DAC; Sigma Delta Modulator; DDFS;

    Abstract : The network latency in fifth generation mobile technology (5G) will be around one millisecond which is much lower than in 4G technology. This significantly faster response time together with higher information capacity and ultra-reliable communication in 5G technology will pave the way for future innovations in a smart and connected society.

  4. 4. Linear Interpolation D/A Converter Applied to Direct Digital RF Modulators

    Author : Zhou Yijun; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; SOC.; quadrature modulator; interpolation; filter; DSP; CMOS; DAC;

    Abstract : This thesis deals with techniques for the full integration of radio frequency (RF) transmitter with CMOS technology. The theory and implementation of high performance digital-to-analog converters (DACs) for radio frequency (RF) transmitters have been studied. A linear interpolation DAC architecture is proposed.

  5. 5. CMOS Data Converters for Closed-Loop mmWave Transmitters

    Author : Victor Åberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; SAR ADC; IQ-modulator; Data converter; mmWave; RF-DAC;

    Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.
