Optimal Training Signals for MIMO OFDM Channel Estimation in the Presence of Frequency Offset and Phase Noise

Overview The authors develop robust Mean-Square Error (MSE)-optimal training signal designs for multiple-input multiple-output orthogonal frequency-division multiplexing channel estimation with frequency offset and Phase Noise (PN), and present analytical and simulation results for the frequency-offset and PN effects on channel estimation. The proposed designs are more advantageous for moderate-to-high values of Signal-to-Noise Ratio (SNR), residual frequency offset, and PN level.

Peter Cochrane's Uncommon Sense: Wireless everything

Each signal is allocated different time and micro-frequency relationships that can only be unscrambled by an a priori knowledge embedded in selected receivers. The electronics to operate in 'cocktail party' mode and filter out the desired signal by...

They use the power from the initial radio signal to transmit their response. First, because they broadcast their ID number, a thief could rig up his or her own device to intercept and then rebroadcast the signal to an automatic teller machine.

Citywide wi-fi gets a helping hand

Menezes said Wavion solves these issues by using a version of Mimo, or multiple input and multiple output technology, which uses multiple antenna to send and receive several data streams over the same channel simultaneously.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
