Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] This device considers implementing the CQI decoding and judgment function through hardware, so that the hardware system only needs to report a small amount of data after CQI decoding to the software, thereby greatly reducing the amount of data transmission and storage without affecting system performance; The data after CQI decoding can be transmitted to other hardware modules for further processing, which greatly alleviates the limitation of processing delay.

[0054] Such as image 3 As shown, the channel quality indicator decoding device according to the present invention mainly includes the following functional units:

[0055] The fast Hada code conversion unit 301 is used to realize two functions: the first is to iteratively calculate the sequence formed by the demodulated and operationally processed CQI soft symbol data ...

Abstract

A channel quality identification decoding device of high speed special physical control channel consists of fast Hada code conversion unit for carrying out operation on soft symbol data of channel quality identification and for outputting energy absolute value of said symbol, peak value detection unit for picking up maximum value from said absolute value and for outputting said maximum value and index value of said maximum value, lookup mapping unit for obtaining decoded bit of channel quality identification according to energy value corresponding to said absolute maximum value and said index value of maximum value.

Description

technical field [0001] The invention relates to a channel quality identification decoding device, in particular to a channel quality identification decoding device for a high-speed dedicated physical control channel in a CDMA third-generation mobile communication system. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA for short) is a new technology added to the 3GPP WCDMA Release 5 specification to achieve higher downlink data rates and greater base station capacity. HSDPA introduces new physical channels and a new transport channel. An uplink physical channel is added to the uplink, that is, the High Speed ​​Dedicated Physical Control Channel (HS-DPCCH for short), which is used to carry the Hybrid Automatic Repeat Request (HARQ) acknowledgment (ACK) and Channel Quality Indicator (CQI for short) information. [0003] In HSDPA, the terminal UE measures the downlink physical channel quality, and sends the channel quality indicator CQI to the base sta...
