Extended Abstract: Polarization Differential Pulse Position Modulation
نویسندگان
چکیده
In underwater wireless optical communication links, pulse position modulation (PPM) and differential pulse position modulation (DPPM) are two typical modulation schemes. In this paper, we present an alternative modulation scheme to improve the communication performance compared with the traditional methods. As an improvement of DPPM, this new modulation scheme, which named as polarization differential pulse position modulation (PDPPM), combines the polarization technology with DPPM scheme. Simulation results suggest that the channel bandwidth efficiency and biterror-rate (BER) performance are enhanced obviously based on our new method.

Multilevel pulse-position modulation for optical power-efficient communication.
A family of modulation formats is derived by combining pulse-position modulation (PPM) with multilevel dual-polarization signal constellations. With 16-PPM, gains of up to 5.4 dB are obtained over dual-polarization QPSK, at the cost of reduced spectral efficiency.

In this study, a new adaptive controller is proposed for position control of pneumatic systems. Difficulties associated with the mathematical model of the system in addition to the instability caused by Pulse Width Modulation (PWM) in the learning-based controllers using gradient descent, motivate the development of a new approach for PWM pneumatics. In this study, two modified Feedback Error L...

Optical wireless communication has the potential for extremely high data rates of up to tens of Gb/s. In this study, a hybrid modulation technique named adaptive differential amplitude pulse-position modulation (DAPPM) is proposed to improve channel immunity by utilising optimised modulation to channel. The unit transmission rate, channel capacity, peak-to-average power ratio, bandwidth require...

متن کاملDifferential Multi-Pulse Position Modulation for Free Space Optical Communication
In order to improve the laser output power in free space optical communication, it is necessary to improve the power efficiency of laser modulation as much as possible, in the case of the limitation of the laser. In this paper, based on the theory of pulse position modulation (PPM), a differential multi-pulse position modulation(DMPPM) scheme was designed, by consulting the structure characteri...
