    • The present invention provides a channel estimation method and apparatus for use in a mobile communication system receiver. The method and apparatus uses a transmission signal with special structure as provided in the present invention, to estimate channel parameters. The transmission signal according to the present invention comprises a burst. The burst comprises multiple training sequence segments and multiple data segments arranged alternately.

    • 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.

    • 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.

    • For a transmission signal for a wireless communication system and a method and apparatus for performing synchronization processing for the transmission signal provided by the present invention, the principal ideas is that, a synchronization sequence is respectively inserted into a group of transmission datum according to predetermined time offsets to form a group of transmission signals. The synchronization sequences inserted into the transmission datum are obtained respectively by performing a phase modulation for the same known basic synchronization sequence according to the predetermined phase offsets, dispersed in the same transmission signal period without overlapping with each other, and transmitted by different transmit antennas. By using the transmission signals and the structure of their synchronization sequences, the receiver side only needs to search a part of the received signals, then one of an expected group of synchronization sequences, served as the main synchronization sequence, can be acquired quickly, and based on this, the synchronization positions of the transmission signals from other transmit antennas can be estimated, at the same time, by using the phase offsets between the synchronization sequences and the basic synchronization sequence, the transmission signals from different transmit antennas can be distinguished effectively.
