What type of receiver is used for the BPSK detection?
In this paper, a coherent multi-antenna receiver, which does not require a prior information of the ambient signal, for decoding Binary-Phase-shift-Keying (BPSK) modulated signal is presented.
How does BPSK work?
Binary Phase-shift keying (BPSK) is a digital modulation scheme that conveys data by changing, or modulating, two different phases of a reference signal (the carrier wave). The constellation points chosen are usually positioned with uniform angular spacing around a circle.
What is BPSK in data communication?
Binary Phase Shift Keying BPSK
This is also called as 2-phase PSK or Phase Reversal Keying. In this technique, the sine wave carrier takes two phase reversals such as 0° and 180°. BPSK is basically a Double Side Band Suppressed Carrier DSBSC modulation scheme, for message being the digital information.
Which modulation is used to generate BPSK?
Explanation: The BPSK signal is equivalent to a double sideband suppressed carrier amplitude modulated waveform, where cos(2πft) is applied as the carrier. Hence, a BPSK signal can be generated using a balanced modulator.
What type of message signal is used for generating BPSK signal?
BPSK signal may be generated by applying carrier signal to a balanced modulator. Here the baseband signal b(t) is applied as a modulating signal to the balanced modulator. A NRZ level encoder converts the binary dta sequence into bipolar NRZ.
Where is BPSK used?
The BPSK modulation is a very basic technique used in various wireless standards such as CDMA, WiMAX (16d, 16e), WLAN 11a, 11b, 11g, 11n, Satellite, DVB, Cable modem etc. It is considered to be more robust among all the modulation types due to difference of 180 degree between two constellation points.
