To kspalla: Thank you for your reply, it is proper in your case, but for a network, if most of the interfering transmitters are nearer than the desired transmitter. then the severe pathloss will affect the system terribly. On the other hand, if most of the interfering transmitters are farther...
To kspalla: Thank you for your reply, but the loss may be identical to all the users, so the interference is still the same. On the other hand, the pathloss may bring more errors.
Hi, Merry Christmas!
"severe pathloss environments often are desirable in a multiuser wireless network, such as CDMA/WiMAX systems." Can any one tell me why?
Thanks Very much!

Hi, I want to do a project about baseband modem based on FPGA, but I don't know how to select an appropriate chip for it , can any body help?
and the modultation rate is 50Mbps.
Thank u advance!
maybe you can refer to "MATLAB Principles of Communication Systems Simulation with Wireless Aplications, William H. Tranter,K. Sam Shanmugan, Theodore S. Rappaport, Kurt L. Kosbar", there is a example about cdma.
orcad capture error node floating
Thanks!
i tried your suggestions but they dont work. i suspect that the software i installed had some problems. am i right?
maybe i have to try to reinstall the software, is there other way i can try?
Thanks for suggestions!
Today i use the Orcad for the first time to create a simplest circuit, and a pspice simulation profile. i get every exponents linked on the schematics, then i click "run". but the result is :
ERROR -- Node N00171 is floating
ERROR -- Node N01129 is floating
ERROR -- Node N01044 is floating...
