Multi-User Massive MIMO Channel Estimation Based on Kalman Filters

Schöpfer:

Yao, Zhaoda

Abstract:

In wireless communication, channel state information (CSI) is essential for data detection. Fast fading coefficients estimation is important in order to acquire accurate CSI. Kalman filters (KF) are widely used for real time parameter estimation and can be used to estimate the fast fading coefficients of a mobile communication channel....

Channel Estimation in TDD Massive MIMO Systems with Subsampled Data at BS

Schöpfer:

Tian, Yichuan

Abstract:

Massive MIMO is a promising technique for future 5G communications due to its high spectrum and energy efficiency. To realize its potential performance gain, accurate channel state information at transmitter side (CSIT) is essential. Frequency division duplex (FDD) is widely employed by the most cellular systems today. However, it requires...

Non-data aided parametric based carrier frequency estimators for bursty GMSK communication systems

Schöpfer:

Kandukuri, Ajay

Abstract:

Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...

A channelized digital receiver design for UWB sytems in a multipath indoor environment

Schöpfer:

Chang, Yuhao

Abstract:

This thesis presents a channelized digital receiver design for UWB sytems in a multipath indoor environment. The UWB technology has been used for commercial and military purposes due to a number of advantages such as low-power consumption, noise-like and carrier free. The energy of UWB signal is spread over a...
