Embodiment 1

[0047] In this embodiment, the complex number addition and subtraction module is specifically a complex number adder and subtractor group, and the selection module specifically includes: a first selector, a second selector, and a third selector.

[0048] Reference figure 2 , The symbol-level processing device of Embodiment 1 of the present invention includes:

[0049] The complex number adder-subtractor group has two input ports, one output port and one control port. The complex number adder-subtractor group has at least two complex number addition and subtraction operation modes, which are used to control information received according to the control port Select one of the at least two complex number addition and subtraction operation modes, perform complex number addition and subtraction operations on the data input by the two input ports, and output the operation result through the output port;

[0050] The first selector has 3 input ports, two output ports and a control port. On...

Embodiment 2

[0071] Reference Image 6 , The symbol-level processing device of Embodiment 2 of the present invention includes: a complex number adder-subtractor group, a first selector, a second selector, a third selector, a complex number multiplication and accumulation module, and a complex number adder and subtractor.

[0072] The structure and connection relationship of the complex adder-subtractor group, the first selector, the second selector, the third selector, and the complex multiplication and accumulation module in the second embodiment are the same as those in the first embodiment, and the second embodiment is only in the first embodiment. A complex number adder-subtractor is added on the basis of which has two input ports, one output port and one control port. One of the input ports is connected to the output port of the complex number multiplication and accumulation module. The complex number addition and subtraction device has at least two complex number addition and subtractio...

Abstract

The invention provides a symbol-level processing device. The symbol-level processing device comprises a complex addition and subtraction module, a selection module and a complex multiplication and accumulation module, wherein the addition and subtraction module comprises at least two complex addition and subtraction operation modes, and is used for selecting one of the operation modes from the complex addition and subtraction operation modes according to control information received by a control port and executing complex addition and subtraction operation to data inputted from two input ports; the selection module is used for selecting two data from the data inputted from at least two input ports according to the control information received by the control port and outputting the two data respectively from two output ports; and the complex multiplication and accumulation module comprises at least two complex multiplication and accumulation operation modes, and is used for selecting one the operation modes from the complex multiplication and accumulation operation modes according to the control information received by the control port and executing complex multiplication and accumulation operation to data inputted from the two input ports. The symbol-level processing device can lower the complexity of implementation of a receiving system.

Description

Technical field [0001] The invention belongs to the field of mobile communication, and particularly relates to a symbol-level processing device for a wideband code division multiple access system. Background technique [0002] In a wideband code division multiple access communication system, in order to overcome problems such as fading and frequency offset, it is necessary to measure the signal-to-interference ratio in the channel estimation, frequency offset, and power control of the physical channel to complete the RAKE receiver function and the power of the system. Control and other functions. [0003] In the receiving system of the wideband code division multiple access communication system, these measurements are generally done through a specific algorithm using multipath data of a dedicated control channel. In the prior art, specific implementation devices are provided for channel estimation, frequency offset estimation, signal-to-interference ratio measurement, etc., and ea...
