摘要： A light-emitting element includes a light-emitting stack for emitting light and a substrate structure including: a first substrate disposed under the light-emitting stack and having a first surface facing the light-emitting stack; and a second substrate disposed under the light-emitting stack and having a second surface facing the light-emitting stack; and a reflective layer formed between the first substrate and the second substrate and having an inclined angle not perpendicular to the first surface.

摘要： A time division duplex orthogonal frequency division multiplexing (TDD-OFDM) distributed antenna system (DAS), a base station and a remote access unit for the same are provided. The base station performs an inverse fast Fourier transform on a user downlink signal, a transmitting/receiving enable signal and an input control signal to generate a first OFDM signal. The user downlink signal is carried on a used subcarrier set of the first OFDM signal, while the transmitting/receiving enable signal and the input control signal are carried on a guard band subcarrier set of the first OFDM signal. The remote access unit receives the first OFDM signal via a fiber transmission line, switches between a transmitting mode and a receiving mode periodically, performs a clock synchronization with the base station according to the transmitting/receiving enable signal, and performs a system configuration according to the input control signal.
