Constructors are the special type of methods that get called when we create an instance for a class i.e. an object. Constructors are used to initialize the member variables of a class with their default values. Without initializing, we cannot…
IMSI:- IMSI stands for International Mobile Subscriber Identity. Structure of IMSI: The subscriber is identified within the home PLMN using the Mobile Subscriber Identification Number (MSIN). IMEI:- IMEI stands for International Mobile Equipment Identity. Structure of IMEI: TAC (Type Allocation…
The creation of a beam using constructive interference between the signals transmitted by each antenna element is known as beamforming. Beamforming can be done in two ways: Analogue beamforming In analogue beamforming multiple antenna elements are connected to a single…
The creation of a beam using the constructive interference between the signals transmitted by each antenna element is known as beamforming. Using the MIMO technique we can construct a phased array antenna with which based on the antenna spacing and…
MIMO stands for Multiple Input and Multiple Output. Multiple Input refers to Multiple antennas at the transmitter side which can do multiple transmissions into the propagation channel. Multiple Output refers to the multiple antennas present at the receiver end which…
What is a class? A class is an object-oriented paradigm or model used to group both data & functionality together. Classes provide additional features like access restriction which we will discuss in detail while going further. class keyword is used…
Python programming language was created by “Guido van Rossum” and was released in 1991. Python features: Why python is portable? Python is portable because both “python script” (.py) and “python byte code” (.pyc) are platform-independent i.e. you can write once…
