Re: MIMO-OFDM
you should divide the transmitted data into Mt bit stream. after modulation with OFDM you should transmit the modulated signals through MIMO channel
Re: which will cover more distance: Low or high Freq. signal
of course there are some ambiguity in your question. what is your mean of high and low
each frequency band has especial transmission characteristics for example FM is not very high but because of its reflection from the atmosphier, it...
Re: need some help
tracking is a process enable you to chive the target path, distance, angle or its signal frequency, ...
most important tracking algorithms are kalman, particle filter, Alfa Betta Filter
if you make your question more clear, i can better help you
Re: please help me
in DSSS Direct Sequence Spread Specrum a PN code with high bite rate is used to spread the data stream. in this case the data power spread in a wide freq. band. so its detection for non outhorizeds are imposible, is noise protected and ...
Re: What is GIS?
using frequency imaging to achieve different information. each frequency or each sort of frequency band is suitable for especial information
why we need modulation
small size of antenna is mainely because the antenna dimesion is approximately in the order of wavelength.
increasing the mobility of tranceiver is another reason
Re: Rr >Tr ....MIMO
if u review the capasity formulations of MIMO systems, u can see that useing T>R have no effect on the capasity but if u choose R>T u can improve the capasity
