Example embodiments relate to techniques for implementing radar waveform diversity. A technique may involve a radar unit transmitting radar signals into an environment of a vehicle based on a code sequence that indicates a ramp direction and a phase shift for each pulse in a pulse used by the radar unit and receiving radar reflections from the environment. In some instances, the radar unit may leverage antennas in a multiple input multiple output (MIMO) arrangement to further add diversity to transmissions according to spatial code in the code sequence. The technique can further involve using a demodulator to map the environment based on the radar reflections and controlling the vehicle based on the mapping. In some instances, the code sequence is received from a system that is wirelessly providing orthogonal code sequences to multiple emitters.

The disclosed systems, structures, and methods are directed to a spectrally-efficient orthogonal code generation architecture. The configurations presented herein employ a full-set code generation module configured to generate a candidate code group, wherein the candidate code group contains 2 L different codes for a given code length L, a frequency response calculation module configured to calculate frequency response of the codes within the candidate code group and a frequency code searching module configured to search the orthogonal codes within each frequency code group. In addition, the grouping of codes is done on the basis of number of frequency locations and positions, one or more code sets are formed within each frequency code group, codes within code sets are orthogonal in nature and orthogonal codes along with their identifier information are stored in a database forming an orthogonal code list.

Embodiments of this application relate to the field of wireless communication technologies, including the field of Wi-Fi technologies, and provide a pilot symbol transmission method and an apparatus, to reduce a possibility that pilots sent by different users in a network collide. In the method, a terminal device may send a codeword, and the codeword may include a pilot symbol and a data symbol. The pilot symbol may include a non-zero pilot symbol and a zero pilot symbol, and the data symbol may include a non-zero data symbol and a zero data symbol. According to the foregoing solutions, the pilot symbol sent by the terminal device may include the non-zero pilot symbol and the zero pilot symbol, so that the pilot symbol sent by the terminal device is sparse.
