The transmitter consists of modulator, LED driver and LED, and the receiver is composed of photo detector (PD), amplifier, demodulator ... 2. LOS VLC scheme diagram. Figure 3. BER vs. data rate. Table ...

At the time, the concern was that the IF of radio receivers used 10.7 MHz as part of their demodulation scheme. Stations or assignments separated in frequency by 10.6 or 10.8 MHz, according to the ...

Based around TurboConcept's LDPC decoder and Commsonic's adaptive APSK demodulator ... of, receivers. In the ACM scheme, receivers report their forward link signal-to-noise ratio back to the ...

Simulation results show that iterative detection with amplitude-phase demodulator outperforms the existing receiver for dual-stream CE-OFDM, especially for high phase-modulation index and high-order ...

We adopted cross-gain modulation (XGM) in a semiconductor optical amplifier (SOA) for inverse-RZ generation, which allows both low and high levels of RZ optical signal to have a finite pulse energy in ...
