WebApr 8, 2010 · Binary Phase Shift Keying (BPSK) is a two phase modulation scheme, where the 0’s and 1’s in a binary message are represented by two different phase states in the carrier signal: θ = 0∘ θ = 0 ∘ for binary 1 and θ = 180∘ θ = 180 ∘ for binary 0. In digital modulation techniques, a set of basis functions are chosen for a particular ...

WebIn Binary Phase Shift Keying (BPSK), the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, the phase is different by 180 degree. A BPSK signal can be defined as Sepsk(t) = A Cos (21fet + fo if m(t) = 1) A m mt0 where m(t) is the binary information. WebThe Binary Phase Shift Keying is one of the digital modulation methods.
