It's been a few months since the launch of the new forums.  Here are a few thoughts. The thumbsup and beer buttons    If there is one thing that could have a...

In small satellite communication technique we can use optical spectrum (optical (laser) communication system). The common and simplest modulation techniques used...

Light computes any desired linear transform without a digital processor Kinda cool.

HelloI am building up a RF transceiver using integrated up/down converter chip.This particular chip requires a complex Intermediate Frequency as inputs for up conversion...

I asked the question about to recover signal from the real part of IFFT OFDM system before,Recover signal from the real part of IFFT.thanks for the responses from...

I'm simulating a Binary Orthognal Chirp Keying communication system in Matlab, with AWGN channel.Basically I'm sending the bit 0  by transmitting a down-chirp C0[n] ...

I'd like to add an upmixer software module to an existing commercially available DSP (Car Audio) with a Sharc chip. I see the Jtag header on the circuit board...

Can you find the illegal step in the following silly proof? Given: a=b$$ a^2=ab$$$$a^2-b^2 = ab-b^2$$$$(a+b)(a-b)=b(a-b)$$$$a+b = b$$$$b+b=b$$$$2b=b$$
