Wireless receivers: algorithms and architectures
Summary
The students will learn about the basic principles of wireless communication systems, including transmission and modulation schemes as well as the basic components and algorithms of a wireless receiver. They develop an understanding for the wireless channel and system performance and limitations.
Content
Fundamentals
Baseband and passband signals, digital modulation, vector-space representation, matched filtering, maximum-likelihood estimation, performance metrics
Synchronized receiver
Carrier frequency and sampling frequency offset, time- and frequency synchronization, interpolation, equalization, diversity receiver
The wireless channel
Basic AWGN channel, signal propagation and attenuation, fading channels, multipath propagation, Doppler shift
Wideband modulation
Multicarrier communication, orthogonal frequency division multiplexing (OFDM), training based channel estimation and equalization for OFDM, synchronization, tracking, some OFDM based communication standards
Final PROJECT: Accoustic OFDM transceiver
We built an accoustic communication system based on OFDM as final project.
Keywords
