摘要： Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.
摘要翻译：这里描述了用于传送具有多种格式的分组的系统和方法。在一些方面，分组的前导码中的信号（SIG）字段可以指示分组中是否包括诸如扩展SIG字段或SIG-B字段的扩展字段。在另一方面，一个或多个检测器可以用于基于接收到的分组的短训练字段（STF）来自动检测被格式化为至少两种不同格式之一的分组。在一些方面，沿着分组的前导码中的训练场（LTF）可以指示有效载荷是否被重复编码。

摘要： Systems, methods, and devices for wireless communication. In one aspect, an apparatus for wireless communication is provided. The apparatus includes a receiver configured to receive a wireless signal comprising a packet. At least a portion of the wireless signal is configured to be received over a bandwidth lower than or equal to 1.25 MHz. The packet is formed from at least one orthogonal frequency-division multiplexing (OFDM) symbol comprising thirty-two tones. The thirty-two tones correspond to frequency subcarriers within the bandwidth. The thirty-two tones of the at least one OFDM symbol are allocated as: twenty-four data tones, two pilot tones, five guard tones, and one direct current (DC) tone. The apparatus includes a processor configured to evaluate the wireless signal. The processor includes a transform module configured to convert the at least one OFDM symbol into a frequency domain signal using a thirty-two point mode.

摘要： Systems and methods for computing log likelihood ratios in a communication system are described. A demodulated symbol may be received. A set of scalars may be determined based on a modulation order, a signal-to-noise ratio for the symbol, and a bit of the symbol. At least one log likelihood ratio for the bit may be approximated using a piecewise linear process based on the scalars and the symbol.
