sea propagation
hi guys:
I am looking for info in order to calculate a line-of-sight datalink via a sea path. VHF/UHF range. Any equations, books, links are welcome

signal bandwidth
just my 2cents:
greater bandwidth ==> highest sample rate ==> greater 'time resolution'
so, for example, if you have 5Mhz BW and your sample rate is 10Msps then, you can resolve multipaths delayed 100ns (1/sample rate). So you can take the benefits of a great number of...
hi
...indoor propagation is very dependent on a lot of parameters like: frequency, signal bandwidth, Tx-Rx distance, LOS or NLOS conditions, ...etc.
There are some models available on a lot of IEEE papers, basically grouped in Statistical models (based on statistics of measurements) and...
smart antennas on mobile phone
hi dalila:
I think this paper can be useful to you:
"An Overview of Smart Antenna Technology for Mobile Communications Systems"
Lehne et al
IEEE Communications Surveys
h**p://www.comsoc.org/livepubs/surveys/public/4q99issue/lehne.html
...like it establishes, one...
basic of smart antenna
...very interesting research topic ... i think is too difficult to implement a smart antenna in the mobile due to the restrictions on size an power consumption (PA + DSP)
however take a look to:
Design of Diversity Antennas for Mobile Telephones
Rowell & Murch
ISRP 97...
Re: Sounding the Channel.
dear boy:
...please let us know when you have it.
Also, may you recommend some seminal papers, books or basic material about this topic please?
Best regards.
Re: Convolution...
hi
...I think that: " the bandwidth of the multipath channel " refers to the 'coherence bandwidth'. it's mean the bandwidth of the channel with 'flat' response.
So, if BW of the signal > BW coherence then it (signal) will be distorted, BUT
in a little spatial area (local...
hi haulm
-with your mouse select the simulink blocks needed
-click on: Edit / Copy model to clipboard
then, in word:
-click on: Edit / Paste Special
-Paste As: Picture (Enhaced Metafile)
...then format picture as you desire (size, layout, etc.)
hope it be helpful
regards
Software Radio is the future!
... joined to some smart phone terminal (a kind of pda/cellular with multiple functions) = multiple communications standards and multimedia characteristics (audio, video)
so, look for Software Radio and Digital Signal Processing :)
