FM Demodulator Hello, I am working on designing an FM demodulator for a software-defined radio class I am taking. For an earlier lab in the course, I designed an AM demodulator using envelope detection. It is my understanding that it is possible to create an FM demodulator simply by putting a phase detector in front of my pr... 6 Dec 2005 21:52
rayleighchan function in MATLAB Hi All, I was wondering of anyone of you have tried using the function rayleighchan in MATLAB. as it is a channel function I would expact it to generate uncorrelated channel everytime. But surprizingly it generates identical channel realization. So If I have two simulations.. I have identical channel for both of ... 30 Nov 2005 16:49
DVB-H FEC decoder question ... Hello, I was looking at the DVB-H standard which has a serially concatenated encoding with Reed Solomon code (RS(204,188, t=8) from RS(255,239, t=8) ) as the outer code and Convolution code (K=7) as the inner code. At the receiver, I can think of at least four decoding options, 1. Viterbi followed by RS decoder.... 8 Dec 2005 15:40
TI 6713 DSPLIB functions and interruptibility Folks I have been dubugging some software on a 6713 DSK using an FFT. I've isolated the problem down to either (a) running the interrupt driven McBSP codec at more than 24kHz sampling rate or (b) running the fast convolution in the main() function using the TI DSPLIB DSPF_sp_cfftr2_dit function with an FFT size ... 24 Nov 2005 04:57
Space Time Coding Dear all, i am studying the paper Super Quasi Orthogonal Space Time Trellis Codes by Hamid JafarKhani. As i am a new bie in the huge world of Space time coding. I have start reading his paper and still in the learning process. I have already simulated Almouti papers which is very interesting. I have to simulate ... 23 Nov 2005 00:25
CVSD source code Where's source code, DSP implementation, & documentation for CVSD vocoder? (16kbps Continuously Variable Slope Delta Modulation military standard) ... 21 Nov 2005 12:03
Repeating data frams in OFDM Q1: This is with reference to the white paper by TI entitled, "Power Line Modem with E-meter Platform", 2004 (i'm sorry i can't find the link to the article) At the part where the paper decribes the Packet Format for the OFDM frames. It says that the data frames are grouped into blocks of 3 frames and each data frame ... 18 Nov 2005 04:18
PM demodulation For my final project at university I'm working on a special measurement hardware. I've a tone at a certain frequency. I want to analyze the phase noise which is present in a bandwidth of 1 MHz around the tone. For doing that, stated that I'm using an FPGA with an ADC and given that the frequency of the tone is... 22 Nov 2005 07:12
quadrature modulator I am working on baseband portion of a software defined radio on a Blackfin DSP platform. Using I and Q signals in the quadrature modulator , I want to try out various modulation schemes like AM, FSK,FM,BPSK,GMSK, QPSK and QAM. I am not very familiar with MATLAB. I would like some help on simulation of the quad modlr bl... 25 Nov 2005 08:22
