    • A multiple-input multiple-output multi-band OFDM transmission system (400) employs a data interleaving arrangement that is backwards compatible with specifications for a legacy interleaver. In one embodiment, an input data stream is parsed into two or more separate data streams by a round robin parser (310) and each of the separate data streams is shifted by a corresponding number of symbols and then interleaved by a legacy interleaver (340i). In another embodiment, data for a plurality (N*i) of symbols is split into N sequential groups of data, each group corresponding to one of N MIMO spatial streams, each stream including data for i symbols. Each group is then interleaved by a legacy interleaver (520i). In a third embodiment, an input data stream is interleaved by a scaled version of the legacy interleaver (610), and then parsed by a round-robin parser (620).
    • 多输入多输出多频带OFDM传输系统(400)采用与传统交织器的规范向后兼容的数据交织布置。 在一个实施例中,轮询解析器(310)将输入数据流解析成两个或更多个单独的数据流,并且每个单独数据流被移位相应数量的符号,然后由传统交织器(340i)进行交织, 。 在另一个实施例中,用于多个(N * i)个符号的数据被分割成N个连续的数据组,每个组对应于N个MIMO空间流中的一个,每个流包括用于i个符号的数据。 然后,每个组由传统交织器(520i)进行交织。 在第三实施例中,输入数据流由传统交织器(610)的缩放版本交织,然后由轮询解析器(620)解析。

    • The present invention provides a system (600), device (500) and method (400) for automatic partner selection in an existing Cooperative MAC (CMAC) protocol, which uses the Ready-to-Send (RTS), Clear-to-Send (CTS) and Partner-Clear-to-Send (PCTS) handshaking to establish cooperation. The present invention enables a ''best'' partner/relay (500.R.k) who is also willing to cooperate to relay information to a destination (500.D.J) for the transmitting device (i.e., the source), without the source (500.S.i) making a decision on partner selection. That is, the present invention provides a new mechanism by which the best partner/relay (500.R.k) that is also willing to cooperate will ''step in'' automatically without the source's involvement in selection of the partner/relay (500.R.k). This mechanism is contention-based and the partner is ''selected'' using local information only in a fully distributed manner.
    • 本发明提供了一种用于在现有协作MAC(CMAC)协议中自动配对选择的系统(600),设备(500)和方法(400),其使用即时发送(RTS),清除发送 (CTS)和Partner-Clear-to-Send(PCTS)握手建立合作关系。 本发明使得也能够合作的“最佳”伙伴/中继(500.RK)将信息中继到用于发送设备(即,源)的目的地(即,源),而不需要源( 500.Si)决定合作伙伴选择。 也就是说,本发明提供了一种新机制,通过该机制,同时愿意合作的最佳伙伴/中继(500.RK)将自动地“进入”,而不需要来源参与对方/中继的选择(500.RK)。 RK)。 这种机制是基于争用的,合作伙伴只能以完全分散的方式“使用本地信息”进行“选择”。
