Embodiment Construction

[0025] see figure 1 , figure 1 It is a schematic diagram of an embodiment of a diversity receiving system (diversity receiving system) 100 of the present invention. The diversity receiving system 100 includes a plurality of receivers (receivers) 110 , 120 , and 130 connected in series. Each receiver combines at least two sets of weighted bit metric streams (the source can be demapped from more than two sets of radio frequency signals) to output a combined bit metric stream ), and the diversity receiving system 100 outputs the final combined bit metric data stream (final combined bit metric stream) generated by the last receiver 130 . In this embodiment, taking the merging of two sets of bit metric data strings as an example, each receiver combines its own weighted bit metric data string with the merged bit metric data string from the previous receiver to output the corresponding The merged bit metric data string at this stage. Please note that this embodiment takes three g...

Abstract

A series-connectable diversity receiving system and method thereof, the diversity receiving system includes a plurality of receivers connected in series, and the plurality of receivers are used to combine a plurality of weighted bit measurement data strings to obtain from the plurality of receivers A final receiver of the converter outputs a final merged bit metric data string. Each receiver includes: a tuner, and a demapping and combining module. The tuner is used to receive a radio frequency signal and select a predetermined channel from the radio frequency signal to generate an analog input signal. The demapping and merging module is used to perform demapping and merging operations according to the analog input signal of the tuner and a previous merging bit measurement data string, so as to generate a combined bit metric data string. The invention not only improves the transmission efficiency of the diversity receiver, but also reduces the hardware purchasing cost during the upgrade because of the feature of flexible design.

Description

technical field [0001] The present invention relates to a receiving system and its method, in particular to a diversity receiving system and its method. Background technique [0002] After the rise of information products and digital home appliances, various wireless communication products have gradually become popular in daily life, and multimedia applications with a huge amount of data are constantly being introduced, which has promoted the use of wireless communication products to increase the data transmission rate (data rate) demand. In addition to the data transmission rate, the transmission performance is also a very important consideration. Taking the terrestrial digital television broadcasting system (Digital Video Broadcasting-Terrestrial, DVB-T) as an example, the fastest transmission rate is about 3,000 per second. 10,000 bits (30Mbit / s), however, for some channels (channel), the quality of its transmission performance cannot be guaranteed, especially in mobile ...
