A link budget accounts for all the gains and losses from the transmitter to the receiver. It ensures that the received signal strength is high enough to be decoded accurately over the noise floor. 3. Modulation and Demodulation Techniques
Data inside computers exists as binary 1s and 0s. To transmit this data wirelessly, it must be superimposed onto a high-frequency "carrier" wave. This process is called modulation. Basic Analog and Digital Modulation
Using Multiple Input, Multiple Output antenna arrays. By using multiple antennas at both the transmitter and receiver, systems can stream different data chunks at the exact same time over the same frequency, multiplying network capacity. 5. Evolution of Wireless Standards wireless communications from the ground up pdf
Wireless Communications from the Ground Up: An SDR Perspective
Here are a few popular textbooks on wireless communication that are available in PDF format: A link budget accounts for all the gains
Many versions include snippets of Python or MATLAB that simulate what you just read. For example, after explaining BPSK, the PDF shows you how to generate a random bit stream, modulate it, add noise, and demodulate it in 20 lines of code.
: Assigns unique mathematical codes to separate user data on the same frequency. Basic Analog and Digital Modulation Using Multiple Input,
Wireless communication systems can be broadly classified into several types, including:
As the founder of the website Wireless Pi (wirelesspi.com), Chaudhari has built a community around his core teaching philosophy: explaining technical concepts through beautiful figures, simple mathematics, and intuitive reasoning. He is also the author of another widely praised book, , which applies the same accessible approach to the latest generation of cellular standards.
Modulates both amplitude and phase simultaneously, allowing modern Wi-Fi and 5G networks to pack massive amounts of data into a single wave. Error Correction and Detection
: Wireless channel modeling, equalization, and Orthogonal Frequency Division Multiplexing (OFDM).
