I do not know your exact setup so I do not understand all of your explanation but I can give you some hint to debug your problem. -First of all use an ideal...
Went to see my project supervisor today, he cast some doubt on my understanding of OFDM...hope u guys can clarify for me.. Lets say i have a string of bits [1...
Answer to Q1: you are right. it is inefficient both in terms of power and spectral efficiency to transmit only 1 bit per OFDM sym while repeating the bit on...
Regarding your 2nd question, I think, 1st option is correct as it allows the consequtive data bits to be transmitted on different carriers and if some carriers...
Hello, OFDM is a very general concept, and the options are wide open. But a common practice in modulation is more close to your version. Instead of one bit...
Hello, I am trying to implement chase decoder-2 for soft decoding of Block codes and product codes. I implemented the algorithm, but my problem is while...
Our company, Pentum Group, Inc. is looking for for an FPGA software engineer to develop and architect a floating point FPGA library. This library is to be...
Dear Friends, I have TMS320F240 DSP processor.I want to run it contineously .I run a program in step mode.It is working.How I can run it in contineous...
Hi suraj , Thanks for your help. With your help i am able to solve the problem of DFE. I finish my simulation for QPSK. But now i am going to start the...
Yes rajai, my simulation converts the data into complex form before transmission. I use 1s and 0s in my previous query was because my supervisor and i were ...
Sai Did you mean the ML codeword by the right candidate? It is true that the codeword (among the codewords in the subset formed) that is at the smallest ...
Hi, i'm currently doing my undergraduate project on Design and Development of a High-Speed Power Line Modem. The transceiver will be designed in Simulink and...
Hi There are some webinars available in the mathworks website where they discuss ur topic... try www.mathworks.com and look for webinars and see the archived ...
Instead of just looking at the sign of the signal now you will have to compare it with a threshold. If you know the answer for QPSK then its nothing much...
Hi guys, i have a question regarding power line communication to ask. Lets say an indoor power line network. There are N number of sockets. PC A is plugged...
I am in search for the book on dsp by avtar singh and srinivasan can anybody tell me about this book and any link to find the book online as i a wuld be...
hi friends.... currently im doing a final year project regarding to digital watermarking using DWT algortithm.. i really hope to those people have or want any...
The signal is being multicasted around the network in this case the network being your electrical wiring around the home this is almsot like using an ethernet...
Hello, I use 3 stages filter with 3 IIR. I work on DSP TMS320 F2811 . *Input data are 16 bits and i use TI IIR library. I have the following problem : The...
There are quite a few papers in IEEE Xplore on digital watermarking Have a look. There are also different approaches for watermarking an image, do you know ...
thanks for your suggestion. i've notice about those papers but my thesis is focusing on DWT algorithm. do you have any idea how to implement DWT algorithm in...
hello all, I want list of companies which work in DSP and video/audio codec and are based in pune. Right now i am working at Banglore and having 2 yrs of...
Hi, I am able to cancel noise using mono input but not with stereo input.. is there any way out to do noise cancellation on stereo inputs(2 channel) chetan...
there is a paper which can prove helpful to u Huang Daren, Liu Jiufen, Huang Jiwu, Liu Hongmei. "A DWT-BASED IMAGE WATERMARKING ALGORITHM," also u can take a...
1.For the given set of specifications, why the order of Chebyschev filer is less than the order of Butterworth filter? 2. What are Eigen function & Eigen...
... If you are implementing this in Matlab, here is the syntax. Use the Help menu for the details as well as the explanation of the 2D DWT on images about dwt2...
Hi, I am looking for information on Motion JPEG (M-JPEG). I am not able to find a standard by this name. MJPEG is different from MPEG in the sense that it does...
hi can u more eloborate i have cancelled noise ,r u talking about real time implementation in matlab,or on some dsp processor . rucpm <chetanmz@...>...
