    • A parallel scrambling system comprises an M-bit (M>1) interleaved parallel scrambler for parallel scrambling input signals and an M-bit interleaved multiplexer for multiplexing output signals from the M-bit interleaved parallel scrambler. With this arrangement, an M-bit interleaved parallel scrambling of input signals is carried out prior to a multiplexing thereof. The parallel scrambling system also comprises an M-bit interleaved demultiplexer for receiving a parallel scrambled and multiplexed signal from the M-bit interleaved multiplexer and demultiplexing it and an M-bit interleaved parallel descrambler for descrambling output signals from the demultiplexer to make original signals recover. As the scrambling of input signals is carried out prior to the multiplexing thereof, the scrambler can be operated at the rate identical to the transmission rate of input signals, thereby reducing the manufacture cost and electric power consumption to a minimum.
    • 并行加扰系统包括用于并行加扰输入信号的M位(M> 1)交错并行扰频器和用于复用来自M位交织并行扰频器的输出信号的M位交织多路复用器。 利用这种布置,在其多路复用之前执行输入信号的M位交织并行加扰。 并行加扰系统还包括一个M位交织解复用器,用于从M位交错多路复用器接收并行加扰和复用的信号,并对其进行解复用,以及M位交织并行解扰器,用于对来自解复用器的输出信号进行解扰,使原始信号恢复 。 由于输入信号的加扰在其复用之前进行,所以可以以与输入信号的传输速率相同的速率操作加扰器,从而将制造成本和电力消耗降至最低。

    • An apparatus and a method for a random access scheme for multi-channel in a wireless communication system are provided. The method for performing the random access scheme for the multi-channel in the wireless communication system includes randomly generating a backoff counter value to transmit data; adjusting the backoff counter value by taking into account status of a plurality of idle subcarrier sets per backoff slot; when the backoff counter value becomes zero, selecting one or more subcarrier sets to carry the data from the idle subcarrier sets; and transmitting the data through the selected one or more subcarrier sets. The data collision probability between the terminals can be lowered, the channel utility can be enhanced, the transfer rate in the single-channel random access scheme can be raised, and the consumption of the radio resource can be reduced without using signals for the band request and allocation.
