    Abstract: A MIMO ARC transmitter derives demux streams (15, 20) carrying different parts of the information, at given data rates, processes each demux stream by coding and modulation (25, 30) before transmission over the channels, and varies (50, 165) the coding or modulation according to channel conditions, and controls the data rates (50, 155) according to conditions of the channels independently of the variations in coding and modulation. The separate control of processing and of data rates for each demux stream can provide a better balance of rapid response to changing conditions and efficiency in less rapidly changing conditions. The frequency of updating the processing can be limited since these take more time to adapt in the receiver. Sensitivity to rapid changes can be achieved by the data rate changes since these involve less overhead than changes in the processing.

    Abstract: An architecture for midamble generation in communication system, in this architecture, a set of identical bi-directional Partial Cyclic Shift Registers (PCSRs) are used to shift different segments of basic midamble codes in parallel, and the sum length of all these bi-directional PCSR is equal to the length of final midamble sequence. In the present invention, the basic midamble codes are periodically extended and loaded into these PCSRs as the original codes of a special sequence. Simultaneously, a comparator is used to control the shift direction and the degree of shift steps. When this architecture accomplishes all the shift operation, all the special sequence in these PCSRs is downloaded as final midamble sequence. This architecture has higher device reuse ratio and lower gate resource cost.

    Abstract: A software-defined radio system processes radio signals on multiple radios according to a task scheduling method. The scheduling method includes assigning a priority value to each received radio packet, the assigned priority value reflective of preset radio preferences and risk of radio packet loss, and determining a processing execution order for the received radio packets according to earliest associated processing deadline. If there is sufficient time to process each of the radio packets in the processing execution order ahead of their associated processing deadlines, the radio packet are so processed. Otherwise, the radio packet having the lowest priority is abandoned, the radio packets are re-ordered, and time sufficiency is re-checked.

    Abstract: The invention provides a lighting device comprising a light source unit (50), a ventilator unit (30) and a heat dissipating unit (40), wherein the heat dissipating unit comprises a main body (400) having a first surface (401) and a second surface (402), at least one first aperture (403), at least one second aperture (404) and a first set of fins (405) attached to the second surface. The at least one first aperture is formed by perforating the first surface and the second surface, and the at least one second aperture is located around the at least one first aperture at a distance therefrom. At least one fin is configured in arc shape extending from the first aperture toward the second aperture and the ventilator unit is positioned to cover at least part of the fins. Thus, the heat dissipating efficiency is improved because a greater airflow passes through the heat dissipating unit due to a high flow speed resulting from the low resistance.

    Abstract: A multi-protocol, multi-standard, software-defined radio (SDR) includes one or more RF front ends to support each radio frequency band, and a programmable processor that replaces special-purpose hardware for the tuning and demodulation of each radio service. The programmable processor has limited peak processing capabilities, and calculations are made to see if present user terminal assignments will result in processing conflicts that could exceed the peak processing capabilities. In traffic slot applications in particular, any possible simultaneous arrival or overlap of traffic slots from the respective radio services is projected. If conflicts will result from the current user terminal assignments, then those assignments are reshuffled to obtain a non-conflicting result.

    Abstract: In order to reduce the complexity of complex signal correlator and realize algorithm optimization, the present invention provides a method and an apparatus for implement complex signal correlation by means of shifter and adder instead of complex multiplier. In the method, the amplitude and radial angle of a corresponding received symbol is firstly adjusted based on a pre-stored local reference symbol. Then, the radial angle of the adjusted received signal is rotated based on a corresponding interchange indicator. Finally, all the processed received signals are combined to obtain a final complex correlation signal. With this method, the chip size and computing load can be greatly reduced.

During a centralized short period, each terminal sends a probe message including a predefined sequence to a network device and the network device estimates the channel characteristics for each sub-carrier with respect to each terminal by estimating the received probe message. In this way, sub-carrier allocation can be improved and sub-carriers with good channel characteristics are allocated to appropriate terminals.
