Re: Need Google maps
1.
**broken link removed**
check if this helps.
2. Have you decided how map matching process (algorithm) you are going to implement? just as a curiosity!
1. you dont need to extract the signal at the receiver ( i mean no physical operation required for extraction before correlation)
i) when you do the correlation of available PN sequence codes from set (user is for sure going to send code from this set) with the received signal (which is sum of...
(just an idea)
As the CDMA codes are orthogonal. If we correlate all the PN codes with received signal (considering that received signal is time aligned. Otherwise algo needs extension to consider delay or non-alignment), we will get different power level for all the available PN codes.
Now set...
Instead of just implementing signal chain, Consider anything specific like (this is relating to Layer-1)-
1. Channel estimation for WiMax pilot scheme in DL UL
2. MIMO/STC detection schemes from WiMax point of view
3. Ranging code decoding algorithms are receiver (UL)
4. HARQ implemenations in...
Re: Kalman filter
1. Filter design - find out the states of your system
2. Calculate Q and R. (Robert brown and Patrick Hwang book is a material good on this)
3. There is also lot in tuning.
But before all these your state-space design of the system should be available
Re: finding proposal
१. You can consider Adaptive multi beam antenna related projects.
2. specific application antennas for emerging technology like WiMax
enc28j60 guide
I am not sure if this helps-
1.To go about, you should be able have connection between two system (physical connection) to test. Proper cable. If you are connecting PCs directly then crosswire connection cable.
2.Implement the code which will run on both machines (with proper...
yes that is good (Paulys' post). you need test vectors to make sure that you have got correct implementation.
Although, implementing WiMax as a full standard (even if only for Layer-1) as a academic project is difficult. First do some study. List out the features (modulation schemes, FEC...
Re: counter GPS
can you please explain what do u mean by counter GPS?
Do you want to avoid GPS?
or do you want to use GPS as time measuring instrument (use as a counter)?
Re: What is UL-MAP?
DL map - gives information for current frame structure. as user (receiver, MS) doesnt know about encoding of DL map, DL map starts at fixed location and with fixed encoding scheme (layer-1). mac layer at receiver decodes DL map and gives information to PHY to decode the...
1. if you want to plot data on different figure each time, insert 'figure' statement in your code as --
for i=1:10
% get data
figure;
plot(data);
end
2. if you want to plot data in the same plot you can use hold on and plot data
figure;
hold on;
for i=1:10
% get data
plot(data);
end
hold...
Re: navigation sensor
thanks for reply.
If I want GPS outage of 5-10minutes.
The sensor cost be $10-20 each gyro and accelerometer.
Then what should be the noise level, %bias and other specifications for sensor selection.
