Filter requirement. endobj It is almost as efficient as the SSB . AM Modulation Vm is the modulating signal . In our scheme, the orthogonally polarized OSSB signal is achieved using a dual-polarization quadrature phase shift keying (DP-QPSK) modulator without an optical band-pass filter (OBPF). Theoretically, we can get one sideband frequency component completely by using an ideal band pass filter. << /ProcSet [ /PDF /Text ] /ColorSpace << /Cs2 8 0 R /Cs1 7 0 R >> /Font << stream The U.S. Navy experimented with SSB over its radio circuits before World War I. SSB first entered commercial service on January 7, 1927 on the longwave transatlantic public radiotelephone circuit between New York and London. So practically, easy to design filters can be used . 4 0 obj Let us consider a single tone modulating signal as : Eeng 360 * Single Sideband (SSB) Modulation An upper single sideband (USSB) signal has a zero-valued spectrum for A lower single sideband (LSSB) signal has a zero-valued spectrum for SSB-AM – popular method ~ BW is same as that of the modulating signal. Kay sir ace ni kapa mo The process of suppressing one of the sidebands along with the carrier and transmitting a single sideband is called as Single Sideband Suppressed Carrier system or simply SSBSC. /F1.0 9 0 R >> >> In both cases the transmission bandwidth (B T) is occupied by the upper sideband (USB) and lower sideband (LSB). We propose and experimentally verify a novel approach to achieve phase-coherence orthogonally polarized optical single sideband (OSSB) modulation with a tunable optically carrier-to-sideband ratio (OCSR). SS… Generation & demodulation. However, practically we may not get the entire sideband frequency component. Vestigial sideband (VSB) modulation. 14 0 obj In radio communications, single-sideband modulation (SSB) or single-sideband suppressed-carrier modulation (SSB-SC) is a type of modulation used to transmit information, such as an audio signal, by radio waves. Vestigial sideband modulation.
