Abstract: In a transmitter apparatus, a known reference signal is superimposed on top of a data signal that is typically not known a priori to a receiver and the combined signal is transmitted. At a receiver, an iterative channel estimation and equalization technique is used to recover the reference signal and the unknown data signal. In the initial iteration, the known reference signal is recovered by treating the data signal as noise. Subsequent iterations are used to improve estimation of received reference signal and the unknown data signal.

Abstract: Coding gains can be achieved by encoding binary data directly to multi-dimensional codewords, which circumvents QAM symbol mapping employed by conventional CDMA encoding techniques. Further, multiple access can be achieved by assigning different codebooks to different multiplexed layers. Moreover, sparse codewords can be used to reduce baseband processing complexity on the receiver-side of the network, as sparse codewords can be detected within multiplexed codewords in accordance with message passing algorithms (MPAs).

Abstract translation: 可以通过将二进制数据直接编码到多维码字来实现编码增益，这避免了常规CDMA编码技术所采用的QAM符号映射。 此外，可以通过将不同的码本分配给不同的多路复用层来实现多址。 此外，稀疏码字可以用于降低网络接收机侧的基带处理复杂度，因为可以根据消息传递算法（MAs）在多路复用码字内检测稀疏码字。

Abstract: A method for network coding of packets between End Nodes (ENs) and a Relay Node (RN) in wireless communications can be performed at the RN. This method may include: receiving a new packet at the RN from one of the ENs; determining the source node of the new packet at the RN; providing a buffer for each EN; determining whether the buffer associated with an EN that is not the source of the new packet (non-source buffer) has an existing packet buffered and based upon such determination, either: (1) storing the new packet in the EN buffer that is the source of the new packet on a condition that the non-source buffer is empty; or (2) network coding the new packet with the existing packet in the non-source buffer.

Abstract: Methods and systems for communicating in a wireless network may distinguish different types of packet structures by modifying the phase of a modulation constellation, such as a binary phase shift keying (BPSK) constellation, in a signal field. Receiving devices may identify the type of packet structure associated with a transmission or whether the signal field is present by the phase of the modulation constellation used for mapping for the signal field. In one embodiment, the phase of the modulation constellation may be determined by examining the energy of the I and Q components after Fast Fourier Transform. Various specific embodiments and variations are also disclosed.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for an access point (AP) that may identify a pending communication for a wireless device and transmit a wakeup message comprising a device specific identifier to a wakeup radio of the wireless device. The wakeup message may include a preamble, a signal field, and a data field. In some cases, the wireless device may demodulate the wakeup message using a phase modulated on-off keying (PM-OOK) modulation. After awakening, the wireless device and the AP may exchange data using the primary radio, which may be a wireless local area network (WLAN) transceiver or a wireless wide area network (WWAN) transceiver. The wireless device may receive the wakeup message using the wakeup radio, decode the message to obtain a device specific identifier, and activate a primary radio to communicate with the AP.
