| 摘要 |
The invention relates to a method for indoor communications, the method comprising receiving a signal (Ws) for/from a mobile station (Ms) located inside a confined environment (B), converting the received signal into an optical signal for transmission through an optical connection (C2), splitting the optical signal into at least two substantially identical optical sub-signals, applying a different time delay to each individual optical sub-signal so that the time delay difference between the optical sub-signals is at least one chip length, combining the at least two optical sub-signals with different time delays, and adapting said combined signal for reception by a rake receiver of a mobile station (Ms) or a rake receiver of a base station (Bs).
