    Abstract: In a method and a device (10) for transmitting a digital signal sequence, with a prescribed number of individual signals, over large distances relative to the transmission power, the digital signal sequence is repeatedly sent from a first communication device (1, 1a). A second communication device (2, 2a) receives the repeatedly sent signal sequence, wherein a first series of consecutive individual signals of the repeatedly sent digital signal sequence is received (S1) first, the number of individual signals corresponding to the number of consecutive individual signals prescribed for the digital signal sequence. The sequence of individual signals is converted into a sequence of symbol values representing the individual signals and stored in a register (24). Further sequences of individual signals received at a defined time interval after the first sequence of individual signals are also converted into symbol value sequences and superimposed on the sequence stored in the register (24).

    Abstract: In a PON system, an OLT periodically transmits a channel resource information block specifying a carrier wavelength and a spreading code on a first downstream channel to which a spread-spectrum spreader having a first spreading code is applied; one of ONUs receives the channel resource information block with a spread-spectrum despreader having the first spreading code and transmits a connection request to the OLT, using the carrier wavelength and the spreading code specified by the channel resource information block; the OLT having received the connection request transmits a new channel resource information block specifying a carrier wavelength and a spreading code to be used on an upstream data channel to the requester ONU through the first channel; and the requester ONU transmits data, using the carrier wavelength and the spreading code specified by the new channel resource information block.

    Abstract: A method and system for dynamic memory allocation and sharing in electronic systems. Embodiments include multi-channel signal processing, including continuously receiving multiple channels, wherein each channel comprises a discrete signal, and processing the multiple channels in a signal processing component on a time-multiplexed basis. Processing the multiple channels includes configuring the signal processing component for one of a plurality of operational modes, including allocating a memory into areas for storage of types of data, wherein certain areas are accessed by certain signal processing subsystems in certain manners. Configuring includes configuring the signal processing component to operate in different modes concurrently for different channels.

    Abstract: An optical communication system uses superstructured fiber Bragg gratings (SSFBGs) to encode and decode an optical pulse signal transmitted between two optical communication devices. Each SSFBG has uniformly spaced fiber Bragg gratings, producing a chip pulse train with a uniform phase difference between chips. The phase difference defines a code. There is one SSFBG at one of the two devices and two or more SSFBGs at the other device, using different codes to encode or decode the same optical signal. Using one code to encode and multiple codes to decode, or multiple codes to encode and one code to decode, provides a high signal-to-noise ratio and permits stable performance despite environmental temperature variations. For bidirectional communication, each communication device has at least three SSFBGs, divided into a transmitting group and a receiving group, mounted on a mounting plate with a negative thermal expansion coefficient.
