Embodiments of the present invention disclose a sending apparatus and a receiving apparatus, and a method for sending a physical layer signal, includes: constructing a signal with a frame structure comprising multiple Gasequences, a &#x2014;Gasequence, and a single-frequency sequence of M in length; wherein the Gaand &#x2014;Gasequences are Golay sequences of 128 in length, M is an integer multiple of 128, and the single-frequency sequence comprises M single-frequency symbols and is used to enable a receiving apparatus to estimate an Inphase and Quadrature (IQ) imbalance parameter; and sending the signal with the frame structure.

Method, apparatus and system for sending physical layer signal

Embodiments of the present invention disclose a method, an apparatus and a system for sending a physical layer signal, where the method for sending a physical layer signal includes: constructing a signal frame of a physical layer signal, where the signal frame includes one single-frequency sequence, the single-frequency sequence is used to enable a receiving apparatus to capture the signal frame in a frequency domain according to the single-frequency sequence, and the single-frequency sequence includes a plurality of single-frequency preset symbols; and sending the physical layer signal based on the signal frame. Applying the present invention can facilitate capturing the signal frame in a frequency domain by a receive end, and therefore, not only impact caused by frequency offset is overcome, but also multipath energy may be used effectively to improve performance of capturing.
