    Abstract: In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.

    Abstract translation: 在无线OFDM系统中，可以通过使用被设计为在多个OFDM符号的子载波上分配编码块比特的交织器来减轻相位噪声。 这样做会降低噪声的非平稳特性。 这样的交织器可以是矩形交织器，其将每个块映射到不同的子载波以产生频率分集和不同的OFDM符号，以产生时间分集。 交织符号的一个示例性方法是在交织器的行X和列Y处放置第一符号。 下一个符号放在行X + 1和列Y + 1。 这种交错处理的结果是块错误率的大大降低。

    Abstract: This disclosure describes methods, apparatus, and systems related to a channel estimation field (CEF) for various standards, for example, the 802.11ay standard, for single carrier (SC) MIMO channel estimation. In one embodiment, the CEF can use Golay complementary sequences. In another embodiment, the Golay complementary sequences can be defined similar to Golay complementary sequences definitions that can be found in various legacy standards, for example, the legacy 802.11ad standard. Various embodiments of the disclosure can allow channel estimation in the time domain and/or frequency domain, having small or negligible inter-stream interference. Various embodiments of the disclosure can enable an extendable structure for various M×N MIMO configurations, where M and N are positive integers.
