Embodiment approach 1

[0113] The transmission method, transmission device, reception method, and reception device of this embodiment will be described in detail.

[0114] figure 1 An example of the configuration of the transmission device in this embodiment is shown. The coding unit 151 receives the data 150 and the frame configuration signal 113 as input, performs error correction coding based on the information on the error correction code included in the frame configuration signal 113 , and outputs the coded data 152 . In addition, the information on the error correction code included in the frame configuration signal 113 is, for example, information on the error correction code, code length, and coding rate. In addition, the code length means a block length.

[0115] The interleaver 153 receives the coded data 152 and the frame configuration signal 113 as input, rearranges the data based on the information of the interleaving method included in the frame configuration signal 113 , and output...

Embodiment approach 2

[0778] In this embodiment, an example of transmitting a plurality of modulated signals from a plurality of antennas including Embodiment 1 will be described. method as an example.

[0779] First, the description will start from the outline of the configuration of the communication device. In this embodiment, the situation considered is Figure 29 Communications office #1 shown with Figure 30 The situation where the communication station #2 is shown is communicating.

[0780] Figure 29 The configuration of communication station #1 is shown.

[0781] The radio unit group 2952 receives the reception signal group 2951 received by the reception antenna group 2950 as input, performs processing such as frequency conversion, and outputs a baseband signal group 2953 . When the radio unit group 2952 uses the OFDM scheme, it can perform signal processing by Fourier transform.

[0782] Signal processing unit 2954 receives received baseband signal group 2953 as input, performs proc...

Embodiment approach 3

[1296] In the method described in Embodiment 2, in the MIMO transmission scheme including Embodiment 1 that transmits a plurality of modulated signals from a plurality of antennas, the transmitting device selects a plurality of antennas to be used in order to transmit a plurality of modulated signals. As for the method, in this embodiment, an example different from Embodiment 2 will be described.

[1297] First, the description will start from the outline of the configuration of the communication device. The situation considered in this embodiment is that Figure 51 Communications office #1 shown with Figure 52 The communication station #2 shown performs communication.

[1298] Figure 51 The configuration of communication station #1 is shown. Additionally, for Figure 29 The same operations are given the same reference numerals, and since this part has been described in Embodiment 2, description thereof will be omitted.

[1299] The antenna setting processi...

Abstract

The invention discloses a transmission method and a transmission device. The transmission method includes: transmitting a first training signal, which is transmitted by changing a weighting parameterfor a DMG antenna, from the DMG antenna, which is a directional multi-gigabit antenna, each of the first training signals including N consecutively transmitted symbols, N being an integer equal to orgreater than 2; and transmitting a second training signal from the DMG antenna, each of the second training signals including N symbols that are continuously transmitted, wherein the polarization of the first training signal is different from the polarization of the second training signal, the first training signal and the second training signal are alternately transmitted, and the first trainingsignal and the second training signal are continuously transmitted.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of 2016 / 07 / 19, an application number of 201680043677.0, and an invention title of "transmission method and transmission device". technical field [0002] In particular, the present application relates to a transmitting device and a receiving device that perform communication using multiple antennas. Background technique [0003] Conventionally, as a communication method using multiple antennas, for example, there is a communication method called MIMO (Multiple-Input Multiple-Output: Multiple-Input Multiple-Output). In multi-antenna communication represented by MIMO, transmission data of a plurality of sequences are individually modulated, and each modulated signal is simultaneously transmitted from different antennas, thereby increasing the data communication speed. [0004] Figure 73 It shows the DVB-NGH (Digital Video Broadcasting-Next Generation Handheld: Digital ...
