The receiver part contain a dual polarization coherent detection where the optical signal is detected and converted into an electrical signal, an OFDM
demodulation dual polarization is used to demodulate the waveform using the inverse transform of that used in the transmitter, a QAM decoder which is used to change the samples into bits.
MCM systems like OFDM
are computationally complex because it uses separate modulator and demodulator for each of its sub-carriers .
The definition of PAPR in the OFDM
system is the ratio of maximum to the average power of the transmitted symbol.
Once the custom OFDM
signal is created in simulation, the SDR transmitter can be designed.
Figure 5 shows block diagram of vertical layered structure MIMO OFDM
system according to which simulation is done.
Forum will be holding its first meeting of the 2002 year in Beijing, China in early April where they will share with the Chinese marketplace information about OFDM
technology and assist in the acceptance of OFDM
technology for broadband wireless communications in Asia.
From a PHY layer standpoint, OFDM
delivers a larger pipe than CDMA-based systems.
His current research interests include optical networks, error control coding, constrained coding, coded modulation, turbo equalization, OFDM
applications, and quantum error correction.
signal has been formed by generating a vector of1A-128 random data points.
PTS and SLM are usually introduced into an OFDM
system to reduce the high peak power.
for LTE, WIFI and WIMAX: Coherent versus Non-Coherent and Cooperative Turbo-Transceivers provides an up-to-date portrayal of wireless transmission based on OFDM
techniques augmented with Space-Time Block Codes (STBCs) and Spatial-Division Multiple Access (SDMA).
As technologies such as mobile digital broadcasting, Wi-Fi, and WiMAX become more prevalent, increasing numbers of engineers are participating in OFDM
