Abstract: Embodiments of this application provide a balance-unbalance conversion apparatus. The apparatus includes an insulation substrate, a first microstrip, a second microstrip, and a conductive ground. The first microstrip includes a first balance signal connection section, a first impedance matching section, and an unbalance signal connecting section. The unbalance signal connecting section is configured to transmit an unbalance signal. The second microstrip includes a second balance signal connecting section, a second impedance matching section, and a ground section. The second balance signal connecting section is configured to transmit a second component of the balance signal. The ground section is configured to connect to a ground signal. The first microstrip, the second microstrip, and the conductive ground are all disposed on the insulation substrate, and a cross-sectional area of at least a part of the first microstrip and/or at least a part of the second microstrip is gradient.

Abstract: A transmission system includes a sending apparatus and N signal channels, where N≥2, and N is an integer. The sending apparatus includes a first apparatus, and the first apparatus is configured to: obtain N to-be-transmitted signals and an encoding coefficient group, where the N to-be-transmitted signals are represented as an N×1 signal matrix X, and the encoding coefficient group is represented as an N×N orthogonal encoding matrix T; process the N to-be-transmitted signals based on the encoding coefficient group to generate N encoded first signals, where the N encoded first signals are represented as a signal matrix Y; and send the N encoded first signals to the N signal channels, where a signal on each signal channel corresponds to an element in a row of the signal matrix Y.
