Abstract:

The course consists of four parts:

The first part will discuss the sampling theorem of analog signals and the classical transfer of analog communication to a digital channel.

This transfer is carried out using pulse modulation of the DM, PAM, PWM, PPM, PCM types.

In particular, the issues of communication rate, bandwidth, and signal-to-noise ratio will be emphasized.

In the second part, various coding methods will be discussed: variable-length source coding, block and convolutional channel coding, and line coding methods.

The issues of error probability, ISI and solutions using various filters will be emphasized.

In the third part, BB digital modulation methods will be discussed, including binary modulations ASK, PSK, FSK

and multi-symbol modulations M-ASK, M-PSK, M-FSK, QAM types.

And also orthogonal multi-carrier modulation OFDM.

Dealing with channel noise for each method will be emphasized.

In the fourth part, BP methods including Spread Spectrum methods will be discussed.

Dealing with channel noise and jamming signals for each method will be emphasized.
