    • A solution for determining in a radio receiver a data sequence indicating transmission parameters and a spreading factor applied to a frame before receiving the whole frame in the radio receiver. According to the provided solution, the transmission parameters and the spreading factor are determined from received data of a partially received data sequence indicating the transmission parameters of the frame. The received portion of the data is despread with known possible spreading factors and the despread data is compared with corresponding data of known possible transmitted data sequences. Spreading factor-data sequence combination resulting in the best match with the received data is then determined to be the most probably transmitted data sequence. The results of comparison with respect to the spreading factor may be combined with another spreading factor determination procedure for more reliable detection of the correct spreading factor.
    • 一种用于在无线电接收机中在接收整个帧之前在无线电接收机中确定指示传输参数和应用于帧的扩展因子的数据序列的解决方案。 根据所提供的解决方案,从表示帧的传输参数的部分接收的数据序列的接收数据确定传输参数和扩展因子。 数据的接收部分用已知的可能扩频因子进行解扩,并将解扩数据与已知可能发送的数据序列的相应数据进行比较。 然后将导致与接收数据最佳匹配的扩频因子数据序列组合确定为最可能传输的数据序列。 可以将与扩展因子进行比较的结果与另一种扩展因子确定程序相结合,以更正确的扩展因子的检测。
