AI Thread Summary
In CDMA systems, users obtain pseudorandom codes from the receiver, which generates a complex PN code that aligns with the transmitter's code. This synchronization is crucial for effective communication in the system. The discussion highlights the importance of matching codes for successful data transmission. Resources like the provided link can offer further insights into the topic. Understanding this process is essential for grasping CDMA technology.

hello every one

Could anyone please help me? I have question about CDMA.

Where does the user get the pseudorandom code from in CDMA system?

thanks

This is out of my area of understanding but here's what http://www.bee.net/mhendry/vrml/library/cdma/cdma.htm"
has to say:
The receiver, as described earlier, generates its own complex PN code that matches the code generated by the transmitter.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
