Full Form of PSK
What is PSK?
Phase Shift Keying (PSK) is a digital modulation technique used to transmit data by changing the phase of a carrier wave. In this method, discrete phase states represent binary or multilevel symbols, making it highly efficient for bandwidth-constrained communication systems. PSK is widely employed in Indian telecommunications, satellite broadcasting, and wireless networks such as Wi-Fi and Bluetooth. The Indian Space Research Organisation (ISRO) relies on variants like BPSK and QPSK for reliable satellite links, while Indian telecom operators use PSK in 4G/LTE and upcoming 5G networks. PSK is also a core topic in engineering curricula across Indian universities, particularly in electronics and communication engineering. Its noise resilience and spectral efficiency make it ideal for digital TV, DTH services, and military communications in India. For competitive exams like GATE, IES, and ISRO scientist recruitment, questions on PSK modulation, constellation diagrams, and bit error rate analysis are common. Understanding PSK helps students grasp advanced concepts like QAM and OFDM, which underpin modern Indian digital infrastructure.
