An FPGA based transceiving synchronization method is demonstrated for Free Space Optical (FSO) communication system
which is discussed separately as the transmitting protocol and the receiving protocol. During the discussion of these two parts
the co-operation of them is also discussed. The transmitting protocol interfaces the outer input data with a parallel port
buffers the input data
encodes the input data stream
serializes the parallel data and outputs the serialized data. It also has an output management unit to manage the activity of each part of the transmitting protocol. The receiving protocol filters and synchronizes the input serial data stream
parallels the serial data stream
decodes the input data
checks received error
handles transmission exception and interfaces the outer receiver with a parallel port. The entire transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. The presented protocol could be taken as "protocol transparent" for outer interfaces
meaning that when interfacing the presented system to an outer system
users don't have to consider what protocol the outer system transceiving data stream is under
for example
the TCP/IP protocol or anything else
in the case that its I/O interface is a parallel port. Simulation and final experiment prove that the protocol presented is a working solution at a certain bit rate scale. 2012 IEEE.

Control and management of the urban traffic signal is an problem that modern city has to face. The traffic signal controller makes a great contribution to the improvement of traffic status and the reduction of traffic jam. A traffic controller is designed using the technology of USB host based on ISP1161A. Universal serial bus is new interface bus architecture for PC
which supports the PnP function Of PC peripheral equipments and has been widely used in computer and communicational devices. ISP1161A complies with the protocol of USB1.1
and is used as the core part of the system. As a new try
the USB host technology is applied into the design of controller to implement the communication with PC. Configuration of scheme is carried out successfully. The USB host technology makes configuration of scheme and future update easier and more convenient. 2011 IEEE.

In order to further enhance the bandwidth of the data communication system in theodolite
The whole design of the PMD is realized by using Xenpak optical module. Its duty is responsible for converting 4-channel parallel 3.125Gbps data stream into a serial 10.3126Gbps data stream
a single channel serial optical transmission system was designed based on the studying of the 10BASE-X Gigabit Ethernet physical layer technology which meets the IEEE standard. The conversion between the 64-bit 156.25MHz TTL signals and the 4 channel 3.125Gbps PCML differential signals is carried out by FPGA
and sending out it in the form of light signals. The experimental results show that data transmission capacity was achieved a 10Gbps in the single-channel optical transmission system. It can conduct short distance transmission. The system delay is about 31lns. The bit error rates no more than 10-12
which satisfies the system demand. 2010 IEEE.

A new transceiving protocol is demonstrated for a Free Space Optical (FSO) communication system
and it's discussed in two parts: the transmitting protocol and the receiving protocol. During the discussion of these two parts
the cooperation of them is also discussed. Different from wired communication
an FSO system modulates the data on a narrow beam of laser transmitting through the free space or the atmosphere
and the protocol presented in this paper is mainly optimized for terrestrial Free Space Optical links
in which the signal channel of the system is mainly the atmosphere. Due to the complex composition and activity of the atmosphere
this signal channel brings in great influence on the transmitting laser in it
for example
the absorption and scattering of the atmosphere molecules and aerosols
the scintillation of received laser power caused by the turbulence of the atmosphere
all of which results in a much higher Bit Error Rate (BER) of the communication system. Thus in designing a protocol for an FSO system
more effort should be taken in the encoding of the data stream
the synchronization of the data stream
error checking and exception handling. The main function of the transmitting protocol includes interfacing the outer input data with a parallel port
buffering the input data
encoding the input data stream
serializing the parallel data and output the serialized data. It also has an output management unit to manage the activity of each part of the transmitting protocol. The main function of the receiving protocol includes filtering and synchronizing the input serial data stream
paralleling the serial data stream
decoding the input data
error checking
exception handling and interfacing the outer receiver with a parallel port. The entire transceiving protocol could be programmed into a single FPGA chip to improve system integrity and reduce the system cost. The presented protocol could be taken as "protocol transparent" for outer interfaces
meaning that when interfacing the presented system to an outer system
you don't have to consider what protocol the outer system transceiving data stream is under
for example
the TCP/IP protocol or anything else
in the case that its I/O interface is a parallel port. Simulation and final experiment prove that the protocol presented is working fine at a certain bit rate scale. 2009 SPIE.
