1. 21. An FPGA implementation of a digital FM modulator.

   University essay from Elektroniksystem

   Author : Henrik Boström; [2011]
   Keywords : FPGA; FM; SDR; frequency modulation; software defined radio;

   Abstract : The increase in speed and density of programmable logic devices such as Field Programmable Gate Arrays (FPGA) enables ever more complex designs to be constructed within a short time frame. The flexibility of a programmable device eases the integration of a design with a wide variety of components on a single chip. READ MORE

3. 22. Using DSP technology to improve sound quality in active speakers

   University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

   Author : Mattias Magnusson; [2010]
   Keywords : ;

   Abstract : Aditus Science has developed a system to improve the sound quality in speaker systems, using DSP technology. Software developed in MATLAB is being used to make measurements of the speakers via microphones. Based on those results, the parameters for the signal processing in the DSP can be set. READ MORE

4. 23. Low-Power Low-Noise IQ Modulator Designs in 90nm CMOS for GSM/EDGE/WCDMA/LTE

   University essay from Institutionen för systemteknik

   Author : Mattias Johansson; Jonas Ehrs; [2010]
   Keywords : RF; ASIC; Analog Integrated Circuit; IQ Modulator; IQM; CMOS; 90nm; Predistortion; Mixer; Envelope Tracking; Direct Conversion;

   Abstract : The current consumption of the IQ modulator is a significant part of the totalcurrent consumption of a mobile transmitter platform and reducing it is of greatinterest. Also, as the WCDMA/LTE standards specifies full duplex transmissionsand Tx and Rx are most often using the same antenna, it is crucial to have asolution with low noise generation. READ MORE

5. 24. FPGA Implementation of a Multimode Transmultiplexer

   University essay from Elektroniksystem

   Author : Kaveh Azizi; [2010]
   Keywords : TMUX; Farrow structures; Multimode Transmultiplexer; FPGA Implementation; Farrow Applications;

   Abstract : As the complexity of Very Large Scale Integration (VLSI) circuits dramatically increases by improvements of technology, there is a huge interests to shift different applications from analog to digital domain. While there are many platform available for this shift, Field Programmable Gate Arrays (FPGAs) hold an attractive position because of their performance, power consumption and configurability.
