What is BOCM (binary offset carrier modulation)?

Binary offset carrier modulation where a sign is increased by a rectangular sub-transporter of recurrence equivalent to or more noteworthy than the chip rate. The spectrum of the signal is separated into two sections. BOC regulation is otherwise called a split-spectrum modulation. BOC modulation is to decrease the impedance with BPSK-modulated signal, which has a sinc function shaped spectrum. BOC-modulated signals have low energy around the carrier frequency and two primary spectral lobes further away from the carrier
