Shannon theorem defines the upper limit of bit transmission rate over band limited channel; with no errors or with recoverable errors.
Channel coding : usually adding redundant bit(s) for the sake of detecting (and/or) correcting a specific number of bit errors
So "channel coding & source...
Re: spread spectrum
It is a modulation technique,
Here, the channel bandwidth and transmit power are sacrificed to provide secure communication.
The idea is as follows:
Instead of transmitting a band limited signal with high power above the noise level, the transmitter transmits the same energy...
I think you should begin with C then C++.
From C/C++, you can move easily to any other language.
C and C++ are very strong PC programming languages.
All MS Windows versions, UNIX, and Linux are built using C.
Most of the graphics programs (3D studio MAX, Flash, Adobe Acrobat, PhotoShop …etc)...

DMA stands for "Division Multiple Access"
T: Time
F: Frequency
C: Code
Those techniques are used to allow "Multiple" users to "Access", and communicate over the same channel
TDMA:
Time sharing.
Time is divided to slots, each user is assigned a slot or more each user 'transmit or...
