Abstract

The invention provides an LLR processing method and receiving equipment. According to the embodiment of the invention, only the data of one subframe needs buffer memory before LLR processing, thereby saving the buffer memory size of the data of one subframe and reducing the cost of chips of the receiving equipment. In addition, the power consumption and the processing time delay of the receiving equipment can further be reduced.

Description

technical field [0001] The present application relates to communication technologies, and in particular, to a log-likelihood ratio (Log-Likelihood Ratio, LLR) processing method and a receiving device. Background technique [0002] In a wireless communication system such as a Wideband Code Division Multiple Access (WCDMA for short) system, the receiving device descrambles and despreads the equalized received signal to obtain the first demodulated data of a subframe and store it in a in the buffer unit; then, read the first demodulated data in the buffer unit, perform LLR estimation on the first demodulated data, and obtain the LLR value of the first demodulated data; and then de-interleave the LLR value The second demodulated data obtained in one subframe is stored in another buffer unit for subsequent decoding processing. [0003] However, before and after the existing LLR processing, data of one subframe needs to be buffered, thereby increasing the chip cost of the receivi...
