Dear Members of the list: My question is related to quantization of Linear Prediction (LP) Parameters. I know very well that LP parameters are mapped onto Reflection Coefficients and we get a lattice filter. Now, lets say I have an order K Lattice filter: implying that I've a concatenation of first-order lattice

Hi All, I remember that some of the guys are looking for MATLAB and DSP processor training. Here is the workshop organised by Prof. Dr. K. Subba Rao from Osmania University, Hyderabad for DSP and Signal Processing course. I had attended this course and find very useful. If any of you guys are interested in MATLAB programming and DSP processor programming, you can

*Hi,* * * *Is anybody working on Extended AMR WB( AMR WB+ ) ? Please help me in the following doubts.* * * 1. *is it possible to integrate optimized AMR WB in AMR WB+? If not, are they separate specifications?* 2. *are IF1 and If2 formats required to test AMR WB+? Right now I am having the test sreams which are given

Hello I am working on implimenting amr codec for the 3rd generation of mobile communications on a DSP platform, my code is very long and when I run it by simulator for tms320c55x it taked 20 milion clicks to do one frame!! my first question is that which DSP do you recommend me to use for a code that takes for example 400K bytes.

I'm looking for a robust LP method in noisy environment (around 0dB), which method can get better LP coefficient in harsh noisy background. here is one method named "WLSP" proposed by Alku and Backstrom "All- pole modeling technique based on the Weighted sum of the LSP polynomials" in Proc. IEEE ICASSP'02 orlando, 2002. Have anyone test it?

Hi, Can anybody tell me how to calculate MIPS or MCPS on ARM, Which cycle count has to be considered, is it Total or Core_cycles from Debugger internals->statistics. I used below formula for calculation of MIPS MIPS = Total cycles*Sampling frequency/(No of frames * Samples per frame *100000) Thanks in advance John Ramana P

Hello, I am working on the topic that you see in the subject(3rd generation of moblie communications --> speech coding --> amr (ACELP) encoder and decoder) I have written the c code that is compatible with the needs that we want.and i made it`s decoder and encoder in exe file. now i want to bering it to matlab simulink to make it intarctive. the ne

hi all: i have a speech file 8KHZ and 16bit/ sample, 128kbps. what's the convenient CELP algorithm for this bit rate for the best quality. where can i find the souce code or the application and also for the MELP algorithm. Thanks, Ann

Hi, I am trying to implement the MPEG-2 layer-3 multichannel decoder, backward compatible with MPEG-1 layer-3. I am new to this work and I don't have any source code to implement this decoder, but I got spec 13818-3. Actually I am trying to build this multichannel decoder around the MPEG- 1 layer-3 and its low sampling frequency (lsf) stereo decod

Hi, I work for a Multimedia startup company. we are luking for speech codecs implemented on ARM9 platform for our end system.Can any one give some info abt good companies who does Porting of speech codecs. we need ITU G.723.1 or 3gpp AMR-NB and G.726, G.711. Also cud any tell me how much each codec will cost(in $)so that we can choose the one which fits our bud
