AI Technical Summary

Problems solved by technology

As transmit and receive antennas increase, system complexity, power consumption, and overall cost increase
In addition, traditional signal processing methods on the receiver side of wireless communication systems do not take into account external interference and IPI caused by multipath fading environments

Embodiment Construction

[0060] The present invention provides a method and system for delay matching in a rake receiver. Aspects of the invention may include, in a rake receiver, compensating for at least one or more of the control channel and the data channel before the data channel processes the received data alone and the control channel processes the received data alone. The delays associated with both. Data channels and Dedicated Physical Channels (DPCH) are delayed for a specified period of time relative to control channels. The control channel may comprise a general navigation control channel.

[0061] FIG. 1A is a block diagram of a wireless communication user equipment according to an embodiment of the present invention. Referring to Figure 1A, a user equipment (UE) 60 is shown.

[0062] The UE60 includes a host interface 62, a digital receiver processing module 64, an analog-to-digital converter 66, a filter / gain module 68, a down-conversion module 70, a low-noise amplifier 72, a receive...

Abstract

The invention relates to a method used for time-delay matching in a rake receiver and a system thereof. The method comprises the following steps: in the rake receiver, before a data channel independently processes received data, and a control channel independently processes the received data, time-delay which is related to at least one or two of the control channel and the data channel is compensated. Relative to the control channel, the time-delay comprises a delayed period of time of a common pilot control channel (CPICH), and the data channel or a dedicated physical channel (DPCH).

Description

technical field [0001] The present invention relates to rake receivers, and more particularly, to a method and system for delay matching in rake receivers. Background technique [0002] Mobile communication has changed the way people communicate, and mobile phones have changed from a luxury item to an indispensable part of people's daily life. Although voice communication can meet the basic requirements of people's communication, and mobile voice communication has further penetrated into people's daily life, the next stage of mobile communication development is the mobile Internet. The mobile Internet will become a common source of everyday information, and it stands to reason that universal mobile access to this data should be enabled. [0003] Third generation (3G) cellular networks are specifically designed to meet these future demands of the mobile Internet. With the proliferation and use of these services, factors such as cost-effective optimization of network capacit...
