Milestone 1000+ subscribers 1100+ comments

Those who are regular visitors to dsplog.com might have noticed the small FeedBurner chicklet on the side showing subscriber count showing 1000+ subscribers. Its a nice milestone to reach, one that looked so distant when I wrote the first post stating the objective of this blog on 26th February 2007. We now have around 86 articles with 1100+ comments.

Brief History

Subscribe

The rate of new subscribers improved dramatically once I introduced the free e-Book in October of 2008.

Joining the email subscription list entitles you to receive the free e-Book on Probability of Error for BPSK/QPSK/16QAM/16PSK/64QAM in AWGN.

Future

While writing the posts, making the simulations to work and responding to all those comments, I learned a lot over the last two years. The signalprocessing for wireless comunication is a vast area and we have only just briefly started. I hope to continue to discuss topic relavent to signal processing for comuniction.

I am hoping that reaching the next 1000 subscribers wont take another two years, and for achieveing that I need your help. If each of you can tell atleast five of your friends/colleagues about this blog, it will go a long way in spreading the word about the blog. Thanks in advance.

Over the past 6 to 8 weeks, I know that am guilty of not keeping up with the one past per week target which I have set myself nor am able to respond to comments within 2-3 days. I am not able to squeeze sufficient time for blogging after office work and parenting. I hope to come back to one post per week cycle from the second week of April 2009.

Alamouti STBC with 2 receive antenna

In the past, we had discussed two transmit, one receive antenna Alamouti Space Time Block Coding (STBC) scheme. In this post, lets us discuss the impact of having two antennas at the receiver. For the discussion, we will assume that the channel is a flat fading Rayleigh multipath channel and the modulation is BPSK.
