An electronic device, portable terminal and detection method

Abstract

The invention provides an electronic device, a portable terminal and a detecting method. The electronic device comprises at least one first device interface unit and at least one device signal transceiving unit. Each first device interface unit is used for being connected with a first terminal interface unit of the portable terminal with a terminal signal transceiving unit. The terminal signal transceiving unit is used for transmitting first data of the portable terminal or receiving second data of the portable terminal. The device signal transceiving units are in one-to-one correspondence to the first device interface units. Each device signal transceiving unit is used for receiving first data, from the first device interface unit, of the portable terminal and transmitting the first data or transmitting received second data to the first device interface unit, and the second data is then transmitted by the first device interface unit to the portable terminal. The terminal signal transceiving unit and the device signal transceiving units work simultaneously when the first device interface units are connected with the first terminal interface unit. Data transmitting speed of portable terminals can be increased.

Description

technical field [0001] The invention relates to a multi-input-output terminal, in particular to an electronic device, a portable terminal and a detection method. Background technique [0002] With people's demand for higher data traffic transmitted by terminals, 3GPP has formulated the LTE standard. In order to obtain a higher data communication rate, LTE adopts OFDM multiple access access technology and MIMO multiple input multiple output technology. Among them, MIMO technology is very effective in improving the rate. For example, the maximum downlink rate of SISO single-port input and single-port output can reach 75Mbps, the maximum downlink rate of 2X2MIMO dual-port input and output can reach 150Mbps, and the maximum downlink rate of 4X4MIMO4 port input and output can reach 300Mbps . [0003] MIMO technology needs the support of multi-channel technology, not only the radio frequency circuit channel, but also the antenna. The development of VLSI can integrate some multi...

Problems solved by technology

[0004] The design of one radio frequency channel connected to one antenna does not fully reflect the advantages of LTE; multiple radio frequency channels and multiple antennas, especially the 4X4 antenna configuration, are difficult to achieve in mobile terminals;

[0005] At present, the working mode of simultaneous communication between LTE and voice services requires two antennas, one antenna supports voice and the other supports LTE data, which is difficult to achieve in miniaturized ultra-thin mobile terminals, and diversity reception also faces the same problem
