    摘要: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of preceded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.

    摘要: Embodiments of the disclosure provide auto-detection in wireless telecommunications. Certain embodiments provide or otherwise implement a specific sequence of bits and/or symbols for auto-detection. The specific sequence of bits can be embodied in or can include output codebits from an encoder in a communication device that can send a wireless transmission including the specific sequence. In one embodiment, the encoder can compute or otherwise generate cyclic redundancy checks (CRCs) or other types of validation checks at the communication device. The specific sequence can be determined using the payload of a packet frame. Both the manner in which the specific sequence is generated and the temporal order in which the specific sequence is received relative to other payload in the packet frame can provide specificity to the sequence.
