What is BPSK?

Introduction: The hatchet BPSK represents Binary Phase change Keying. The is digital modulation an approach where inbinary data one and also zero are stood for by adjust in carrier phase by 180 degrees.This is shown in the constellation chart in the figure-1.


In BPSK modulation, every carrier tote one solitary bit thus symbol rate is same to bit rate.BPSK is thought about to be power efficient and not bandwidth efficient.Refer BPSK modulation>> andBPSK vs QPSK>> for moreinformation.

Benefits or advantages of BPSK

Following space the services or benefits of BPSK:➨It is most robust modulation an approach due come the fact that binary 1 and also 0are be separated by 180 degree phase transition of the carrier. Because of this property, BPSK modulated datacan travel longer ranges when transmitted from base station or subscriber stations.Hence BPSK modulation is work in pilot carrier and in preamble sequences.These are supplied for time/frequency synchronization and also channel estimation/equalization purpose. ➨Due to above, BPSK modulation is used by many of the moving towers forlong distance interaction or infection of the data. ➨BPSK demodulator calls for to make just two decisions in bespeak to recuperate originalbinary information. Hence BPSK receiver is very basic compare to othermodulation types. ➨BPSK is power reliable modulation technique as less power is essential to transmitthe carrier through less number of bits.

Drawbacks or defect of BPSK

Following room the flaw of BPSK:➨In BPSK modulation, one bit is carried by one solitary analog carrier.Hence data rate in bits per second is exact same as the prize rate.This is fifty percent in comparison to the QPSK modulation technique and numerous times lesscompare come other greater modulation methods such together 16QAM, 64QAM etc.➨Due to above reason, BPSK is no bandwidth reliable modulation an approach compare toother modulation types.
