Blind OFDM Channel Estimation Using Receiver Diversity

Overview This paper exploits receiver diversity for blind channel estimation for OFDM systems with cyclic prefix. The developed channel estimation algorithm has the following advantages compared with existing blind methods: it is data efficient - the proposed algorithm can be implemented using a single OFDM block; it is computationally efficient - only a single singular value decomposition is required for channel estimation; and it is symbol independent - unlike many existing algorithms, there is no restriction on the input symbol constellation. Cramer-Rao lower bound for the channel estimation is derived to evaluate the performance. This paper shows through numerical examples that the proposed algorithm compare favorably with an existing subspace algorithm.

Three security threats you'll never have heard of

Security expert Wray said although most companies are aware of viruses, worms, Trojans and Denial of Service (DOS) attacks, many IT departments have never heard of such threats as input validation attacks, SQL injection or reverse channel Trojans.

Security Q&A: Your questions answered (Part 3)

You often hear Hotmail, AOL etc proudly boasting that they block spam at the source, so my question is how come I still get so much of it? Companies frequently set up lists of email addresses to block mail from.

Digital signatures could be forged, claim boffins

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?
