Abstract
The invention provides a method to realize the connection between multi-band transceivers trough single receiver channel. To be specific, by using a single receiver channel provided with flexible bandwidth, the invention can enable the receiver channels with different frequency bands to share with each other and thus realize the sharing of hardware resources in the multisystem and to multi-standard as well as the cost saving.
Description
Technical field
The present invention relates to a kind of method that connects by single receiver channel realization multiband transceiver, belong to the radio transceiver field.
Background technology
Along with the development of 3G network, a terminal supports the signal transmitting and receiving of a plurality of frequency ranges to be connected to become demand simultaneously, and the Home eNodeB typical case in this field is just used.
Home eNodeB regularly/synchronously, air interference and on the problems such as switching of family base station, all have higher requirement from traditional macrocell base stations unit, these all will influence the design and the realization of Home eNodeB radio frequency part.Multiband and many standards have more increased complexity for design.
Above-mentioned challenge will occur multi-purpose the time increasing for Home eNodeB, as in order to receive the image position and regularly during this category information, and the listen mode that the broadcast channel near macrocell base stations unit that adds to Home eNodeB is intercepted.What these broadcast channels adopted may be any one common modulation scheme, not necessarily consistent with the used modulation system of Home eNodeB transceiver.Minimum for cost is reduced to, and the component number in the Home eNodeB is dropped to minimum, come to realize that listening functions leaves nothing to be desired if the Radio Resource of main transceiver can be borrowed.Not only can be operated on a series of different frequency ranges in order to ensure transceiver, but also want to handle different modulation classifications.
Summary of the invention
For above purpose, the invention provides a kind of method that connects by single receiver channel realization multiband transceiver, this method may further comprise the steps:
For providing a high performance receiver input to carry out specific main channel signal, the single-channel receiver main channel receives task;
Adopt a low-noise wide-band amplifier to realize the listen mode of all frequency ranges in addition.
Description of drawings
In claims of present patent application, pointed out theme of the present invention particularly, and clearly it has been proposed patent protection.Yet with reference to following detailed description and accompanying drawing, relevant structure that can better understand the present invention and implementation method with and purpose, feature and advantage.
Fig. 1 realizes that by single receiver channel the typical case that the multiband transceiver connects uses
Embodiment
In the following detailed description, having described specific details comprehensively understands the present invention so that provide.Yet the professional and technical personnel will appreciate that the present invention also can implement with other similar details.
IF-FRE selects for use 400kHz to a certain frequency between the 600kHz.Adopting a bandwidth is low pass filter (LPF) about 600-800kHz, guarantees that signal after the ADC conversion by this low pass filter with losing.
Claims (1)
1. realize the method that the multiband transceiver connects by single receiver channel for one kind, this method may further comprise the steps:
For providing a high performance receiver input to carry out specific main channel signal, the single-channel receiver main channel receives task;
Adopt a low-noise wide-band amplifier to realize the listen mode of all frequency ranges in addition.
