xez said:At least those, though often it's necessary to look at
other aspects of things like the signal crosscorrelations,
the protocol retry algorithms / protocol timings / packet or
transmission burst lengths, FEC coding, probability of
simultaneous transmissions, etc. etc.
Basically it depends a lot upon the protocols, the
modulation schemes, and the configurations of the
transmitters/receivers what the actual interference
statistics will be.
T.Engineer said:Please, what do you mean by Protocols?
I am going to use Pulse Position Amplitude Modulation and correlation receiver.
Multiple Access Interference (MAI) refers to the interference that occurs when multiple users are transmitting signals over the same channel simultaneously. It is a common problem in wireless communication systems and can result in decreased signal quality and data errors.
MAI can significantly decrease the performance and efficiency of communication systems by causing signal distortion and data loss. It can also reduce the overall capacity of the communication channel, resulting in slower transmission speeds.
MAI can be caused by various factors, including overlapping frequency bands, improper channel allocation, and signal reflections. It can also occur due to the limited bandwidth of the communication channel and the high number of users transmitting simultaneously.
To reduce the impact of MAI, various techniques can be used, including frequency division multiple access, time division multiple access, and code division multiple access. These methods involve allocating different frequencies, time slots, or codes to different users to avoid interference.
MAI can be measured and monitored using various metrics, such as the bit error rate, signal-to-interference ratio, and carrier-to-interference ratio. These metrics can help evaluate the performance of the communication system and identify potential sources of interference.
