Adaptive transmit eigenbeamforming with orthogonal space-time block coding in correlated space-time channels

Conventional space-time codes can provide a significant improvement in system performance only if the signal paths are spatially uncorrelated, a condition that is hardly met in practice. In this paper, we mitigate this condition by combining a technique of eigenbeamforming, based on the channel correlation matrix, with orthogonal space-time block codes (O-STBC) at the transmitter side of the link. No feedback information from the receiver (the mobile station) is utilized in the proposed structure. Simulation results using 4-ary PSK signaling showed that this idea outperforms existing techniques in both uncorrelated and correlated channels in terms of bit-error rate and symbol-error rate.

Now this is what scientific research should sound like. It almost makes sense, but the specific meaning slides just beyond your grasp, like a tethered lobster trying to pick up a large frozen boiled egg.

[An arbitrary] Eight things you didn’t know about the internet

Is there only one internet? How big is the internet? Who controls it? If it was lost in a forest, would it make a sound, or would it rely on Google maps and end up walking for days down an old dried up river bed until one final dusk, exhausted and staggering it came across a spooky farmhouse with a single light bulb burning on the porch?

Comic chat

In the early days of online chat (1996) Microsoft actually had taste for a moment and got Jim Woodring to design the characters and backgrounds to a product called Comic Chat (same as this post! Amazing!) .

I'm glad they did it, but it would have been a fun meeting at Microsoft

Comic chat was used as the basis for a web comic called jERKCITY. It’s stupid and offensive and funny.

"Slurping and drooling and hurrrrr."

"Slurping and drooling and hurrrrr."

Check out the jERKCITY wikipedia entry! It also gets an entry in Encyclopaedia of stupid, which probably makes more sense.

And it has a cool and kind of offensive video. More than one, but I only watched this one. It reminded me of the time TISM programmed Rage and played the theme to the 7:30 report.

And they have a twitter account. That’s why I like twitter. No other reason.

Which is why MS Comic Chat was created. The end.


And so on and so forth
