Problems solved by technology

When the actual bandwidth of the bus is partially unbalanced, if the processing rate of the MRC unit is faster than that of the symbol-level processing unit, this cyclic reading and writing method will cause the data written by the MRC unit to cover the unread data of the symbol-level processing unit. data problem

Embodiment Construction

[0030] The embodiment of the present invention provides a data processing method and device, which are used to adjust the data processing rate of the units in the RAKE receiver in real time according to the bus bandwidth, so as to realize the dynamic relationship between the actual bandwidth of the bus and the transmission rate of each unit in the RAKE receiver match.

[0031] The embodiment of the present invention relates to the third generation mobile communication system, in particular, relates to a multi-path demodulation of adaptive system bus bandwidth and a hardware resource management scheme of MRC in a WCDMA baseband processing system.

[0032] see figure 2 , the data in the second column of the table gives the interface transmission symbol rate between the multipath demodulation unit and the MRC unit, and the spreading factor SF, the number of multipaths N, and the clock frequency F1 (that is, the multipath demodulation unit and the MRC unit The relationship betwe...

Abstract

The invention discloses a method and a device for processing data in order to realize the real-time adjustment for the data processing speed of each unit in an RAKE receiver according a bus bandwidth and further realize the dynamic matching of an actual bus bandwidth and the transmission speed of each unit in the RAKE receiver. The method for processing the data comprises the following steps that: a multi-path demodulation task group can be determined, and antenna data can be obtained according to the multi-path demodulation task group; and when the obtained antenna data amount satisfies the multi-path modulation demand and the current cached multi-path merging data amount is not exceeded a first preset threshold value, the multi-path modulation can be processed for the antenna data.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data processing method and device. Background technique [0002] Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) is the world's main third-generation mobile communication air interface solution. The uplink supports various rates. For different users, the appropriate block size and transmission can be configured according to the business. Time interval (TTI, Transmission Time Interval). Different block sizes can be selected between TTIs to achieve the purpose of adjusting the data rate. In the R6 version of the WCDMA standard protocol, the high-speed uplink packet access technology is introduced, which makes the minimum spreading factor (SF) allowed by the uplink dedicated data channel reach 2*2+2*4, which greatly improves the user uplink data service rate. With 16 quadrature amplitude modulation (16QAM), it can reach up ...
