Embodiment Construction

[0030] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] In one example, see figure 1 As shown, a multi-carrier expansion processing method, the method includes the following steps:

[0032] S110 The first signal processing unit performs IQ modulation on the data to be sent to obtain each group of single-carrier single-slot IQ data, respectively calculates the shift factor corresponding to each group of the single-carrier single-slot IQ data, and according to the shift factor Each I data and Q data in the corresponding single-carrier single-slot IQ data are shifted and truncated to obtain scaled IQ data corresponding to each group of single-carrier single-slot IQ data, and the carrier sequence number is inserted into After each group of the scaled IQ data is obtained, multi-carrier and same-slot scaled IQ data is obtained, and the first signal processing unit sen...

Abstract

The invention relates to a multi-carrier expansion processing method and system, and devices. According to the multi-carrier expansion processing method and system, and devices, IQ modulation is carried out on to-be-sent data at a sender end; each group of single-carrier single-time-slot IQ data and corresponding shift factor thereof are obtained; multi-carrier same-time-slot zooming IQ data is obtained by employing a time slot dynamic interception method and by setting carrier serial number identifiers, and further power correction and digital upper conversion are carried out, thereby finishing multi-carrier expansion processing at the sender end. At the sender end, the data sent by the sender end is demodulated and decoded by employing the time slot dynamic interception method and by setting the carrier serial number identifiers. On the basis of an RPDIF interface, carrier expansion is easy to carry out on the RPDIF interface, and the performance demand of the system is satisfied. Moreover, the multi-carrier expansion processing method and system, and devices do not influence transceiving of the normal uplinks and downlinks of the sender end and the receiver end, and have good compatibility.

Description

technical field [0001] The present invention relates to the technical field of digital communication, in particular to a multi-carrier expansion processing method, device and system. Background technique [0002] The existing network of the Global System for Mobile Communication (GSM) has insufficient capacity in hotspot areas, cannot meet the demand for sharply increased business capacity, and has insufficient deep coverage due to difficulties in property coordination, and weak ability to absorb traffic in rooms , Network expansion is restricted and other issues. At the same time, in the construction of traditional mobile communication projects, there are often characteristics such as large construction quantities, tight construction schedules, and difficult site selection. In order to alleviate the above problems in a timely manner, operators pay great attention to cellular base station products with large capacity, easy installation, and low cost. [0003] Mindspeed has ...
