Standard-Independent I/Q Imbalance Compensation in OFDM Direct-Conversion Receivers

Overview The growing number of different mobile communications standards calls for inexpensive and highly flexible receiver architectures supporting all standards. The direct conversion receiver is a very attractive candidate to reach this goal. However, unavoidable imbalances between I- and the Q-branch of I/Q demodulator leads to significant performance degradation at the reception of OFDM signals. In this paper a novel compensation algorithm is presented to overcome this problem.

Devil’s Advocate: Profligacy and destruction and IT

Those are just the attributes that are most needed if we are to find a future that does not involve environmental degradation and conflict over scarce resources. But everyone has examples of how this kind of evaluation simply leads to changes that...

Peter Cochrane's Blog: The search for spectrum

But we have a new raft of digital systems being rolled out that have intelligence built into the transmitter and receiver. However, every time I look at the spectrum using an analyser and antenna I find a desert, just a few signals and a lot of...

Peter Cochrane's Blog: Jammers not listeners

When two signals compete, or overlap in the same space, they generally cause problems that manifest themselves in a degradation of picture and/or sound quality. For sure, we don't need to generate a lot of power in the proximity of any system...

Galileo codes cracked by Cornell?

Signals transmitted from Giove-A, short for Galileo In-Orbit Validation Element A, were broken after the researchers intercepted them using a roof-mounted hemispherical patch antenna and a digital storage receiver.

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?
