In acommunication system, the modulation is an important step. Modulation is the process of transmitting a message signal (Baseband signal with low frequency) from transmitter to receiver without changing its characteristics (like amplitude, frequency, phase) by using a carrier signal (high frequency)...
The method involves detecting distortion in a signal which is to be transmitted to a transmission channel (300). The communication system converts information to be transmitted into digital data which are converted into an analogue signal. The analogue signal is modulated using a PAM modulator (...

In this paper, based on the Alamouti space time block codes (STBC) and direct-sequence bipolar pulse amplitude modulation (DS-BPAM) ultra wideband (UWB) system, we investigate the STBC based DS-BPAM UWB system over IEEE UWB multipath fading channels. In order to make the benefits of multip...
and performance analysis [Abstract] Modulation and demodulation is the current signaling an important method in communication system. So-called modulation is a signal to control a parameter of another signal, modulated signal. Demodulation is modulated by the opposite process, recover the original ...
There are many types of privileged accounts that play crucial roles in the IT infrastructure. Let's look at the most common ones. 1. Service Accounts Service accounts are used primarily by software apps and services for interacting with theoperating systemor other software components. These account...
