    • A mobile wireless terminal includes a first wireless unit, a second wireless unit, an audio codec, and a processor unit. The first wireless unit is configured to connect to a wireless relay coupled between the mobile wireless terminal and a phone network over a short-range wireless link. The second wireless unit is configured to connect to a cellular network over a long-range wireless link. The audio codec is configured to process the voice communication. Further, the processor unit is coupled to the first wireless unit and the second wireless unit, and is configured to make a voice communication using the second wireless unit with an external party via the cellular network over the long-range wireless link. The processor unit is also configured to register with the wireless relay to establish the short-range wireless link and, when the registration is successful, to switch from the second wireless unit to the first wireless unit to carry the voice communication with a phone network via the wireless relay.

    • The present invention discloses a method and device for transmitting and receiving a signal in a wireless communication system. The method for transmitting a signal in a wireless communication system according to the present invention comprises: receiving an original data block to be transmitted, the length of the original data block being M, wherein M is an integer; disordering the original data block for one or more times, whereby M data symbols in the original data block are rearranged in each of the one or more times of the disordering, so as to obtain one or more disordered data blocks with length of M; cascading the original data block and the one or more disordered data blocks with a cyclic prefix, to form an equalized signal of frequency domain diversity with time-frequency interleaving; and transmitting the equalized signal of frequency domain diversity through a single carrier.
    • 本发明公开了一种在无线通信系统中发送和接收信号的方法和装置。 根据本发明的在无线通信系统中发送信号的方法包括:接收要发送的原始数据块,原始数据块的长度为M,其中M是整数; 原始数据块一次或多次失调,由此原始数据块中的M个数据符号在一次或多次无序中的每一个中重新排列,以便获得长度为M的一个或多个无序数据块; 以循环前缀级联原始数据块和一个或多个无序数据块,以形成具有时频交织的频域分集的均衡信号; 并通过单载波传输频域分集的均衡信号。
