Design of BPSK/QPSK Modulator using Verilog HDL and Matlab
Quadrature Phase Shift Keying (QPSK) is a modulation scheme commonly used in wireless communication system and it’s because of its ability to transmit twice the data rate for a given bandwidth. In most cases, the QPSK modulator consumes less power and bandwidth in a modern devices but for a system like satellite and mobile devices where their operations are power limited, this is a problem that...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولError-free transmission of microring-modulated BPSK.
We demonstrate the generation of error-free binary-phase-shift-keyed (BPSK) data at 5 Gb/s using a silicon microring modulator. The microring-modulated BPSK signal is propagated at fiber lengths up to 80 km, maintaining error-free performance, while demonstrating resilience to chromatic dispersion. Bit-error-rate measurements and eye diagrams show near equivalent performance of a microring-base...
متن کاملPerformance evaluation of OOK and BPSK modulation schemes for IR-UWB receiver using wide band LNA
Ultra wide band systems are considered as one of the most exciting technologies due to its capability of transmitting data over a wide frequency spectrum with very low power and high data rates. In any UWB receiver the low noise amplifier is the first stage. The LNA plays a crucial role in the whole reception chain. In this paper, we examine the performance of two different modulations techniqu...
متن کاملSimulation of Simulcast for Packet Transmission using MATLAB
In a wireless LAN, received signal strength indication (RSSI) varies in propagation loss, fading, and interference levels depending on the channel. In a single input, single output (SISO) scenario, a transmitter can use redundancy to overcome channel impairments such as fading. However, in a single input, multiple outputs (SIMO) scenario, there is one transmitter and multiple receivers sharing ...
