Re: Graduation Project
If u r an undergrad u can use matlab to develop any simulator like a simulator for rayleigh fading channel. You can find some matlab codes in...
psk_demod matlab code
go through this link im sure ull find it

If you want to see some sample code u can look into this website:

This is a Uni-Polar sequence. so the correlation can be done using XOR
XORin sequence one and two and adding.
0+1+1+1+1+0+0=4
so the correlation is 4
note:
If the XORed sum is zero then the two sequence are said to be orthogonal.
Hope i have answered ur question
Re: Explain the differences between modulation and multiplex
Modulation is for transmission of a signal over an RF band (wireless). eg analog modulation (AM, FM, PM) and digital (ASK,PSK,FSK etc....)
Multiplexing is generally done for parallel communications and is genarally wired.
Hi Adnan,
i think you can start with some thing simple and once u get accustomed to the concepts go for some hifi stuff. A project in Matlab is the best option. Try a simulation for some digital modulation technique etc. you can refer to...
Re: research topics
uwb signalling
COGNITIVE RADIO
TDD CDMA are some good areas of research speacially the first on if u r interested in antena theory. It finds good applns even in the industry
Re: Do probability and statistic have application in electri
ITS USED IN FINDING BIT ERROR RATE OF DIGITAL MODULATION TECHNIQUES,
TO FIND THE STASTICAL CHARACTERISITCS OF THE WIRELESS CHANNEL. WE HAVE VARIOUS DISTRIBUTIONS WHICH SHOW WHAT KIND OF CHANNEL IS GOOD FOR COMMUNICATIONS etc.
Re: Graduation Project
hi,
the hottest topics in wireless today are
cognitive radio
software defined radio
UWB signalling
TDD CDMA is also a good option
i request some one to please tell me where i can find the solution manual for Introduction to Mathematical Statistics, by Hogg, Mckean and Craig.
please buddies its urgent
waht is wireless communication
software defined radio(sdf), Cognitive radio(extension of sdf), MIMO, TDD CDMA, OFDMA are some of the new fields of research
