Sky Wave, Microwave Link Communication and Satellite Communication (SATCOM)

Overview Sky Wave, Microwave Link Communication, and Satellite Communication  (SATCOM) are the focus of this article. Sky Waves are essentially AM waves that the ionosphere reflects. For long-distance communication on Earth, we employ standard microwave link transmission. However, we all know that the earth is not flat, but rather oval in shape. As a result, the signal can only reach a few kilometers on a straight line of sight path (LOS). The signal is then reflected by the earth's surface. But we know that with that microwave link, we can communicate hundreds of kilometers distance. We'll look at how this happens in this article. Terrestrial satellite communication has now replaced microwave relay link communication. Figure: Ionosphere Reflection - suitable for AM band (Sky Wave) 1. Sky Wave You can see how the ionosphere bounces the radio signal and enables the ground station to communicate with the transmitter hundreds of kilometers away. This method is ideal for communica...

Theoretical BER vs SNR for m-ary PSK and QAM

Relationship Between Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) The relationship between Bit Error Rate (BER) and Signal-to-Noise Ratio (SNR) is a fundamental concept in digital communication systems. Here’s a detailed explanation: BER (Bit Error Rate): The ratio of the number of bits incorrectly received to the total number of bits transmitted. It measures the quality of the communication link. SNR (Signal-to-Noise Ratio): The ratio of the signal power to the noise power, indicating how much the signal is corrupted by noise. Relationship The BER typically decreases as the SNR increases. This relationship helps evaluate the performance of various modulation schemes. BPSK (Binary Phase Shift Keying) Simple and robust. BER in AWGN channel: BER = 0.5 × erfc(√SNR) Performs well at low SNR. QPSK (Quadrature...
