Abstract

The invention provides a data receiving method, a transmitting method, a receiving device and a transmitting device. The data receiving method comprises steps: according to a predetermined grouping rule, antennas for data transmission of the terminal are grouped; a grouping result after grouping is notified to the terminal; and data obtained after the transmitted data are processed according to the grouping result and transmitted by the terminal are received, wherein the grouping result is used for enabling the terminal to carry out spread spectrum processing on data on each antenna according to a spread spectrum code sequence corresponding to the group to which the antenna belongs. Thus, the problem that the number of terminals in the data transmission system capable of transmitting data at the same time is limited in related technology is solved, and effects of enhancing the number of terminals in the data transmission system capable of transmitting data at the same time are further achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data receiving method, a sending method, a receiving device and a sending device. Background technique [0002] Direct sequence spread spectrum technology (hereinafter referred to as spread spectrum technology) is widely used in today's communication systems due to its advantages of anti-frequency selective fading, anti-narrowband interference, anti-multipath fading and high concealment, such as Global system for Mobile Communication (Global system for Mobile Communication) , referred to as GSM), Code Division Multiple Access (Code Division Multiple Access, referred to as CDMA) and Long-Term Evolution (Long-Term Evolution, referred to as LTE) systems and the like. The use of spread spectrum technology enables narrowband signals to be transmitted over a wider frequency band, allowing the receiving end to demodulate with a lower signal-to-noise ratio, and it is possible that th...
