Abstract: A base station (100) devised for indoor use in a WCDMA network, comprising a support unit (401) including a power supply unit (303), said support unit (401) being adapted to be attached to a support structure, and a complete base station unit (402) mechanically supported by said support unit.

Abstract: A base station for a WCDMA telecommunications network, intended for use in indoor environment to enhance coverage and increase capacity. The base station is designed according to a modular concept, and includes a base station unit having an interface for connection to a power supply, a radio network contoller, and to an antenna, said base station unit having a sandwich structure comprising a rigid metal back plate, a rigid metal front plate, and a main circuit board attached intermediate said back plate and front plate, wherein said main circuit board is cooled by means of self-convection of said back plate and said front plate.

Abstract: Device for reducing noise in a radio receiver, which radio receiver comprises a transformer (30) having a reference voltage input (20), a radio signal input at a first transformer side, and a radio signal output at a second transformer side, an A/D converter (40) being connected to said second transformer side, wherein a first bandpass filter (50) is connected between said second transformer side and said A/D converter.

Abstract: In a telecommunications network that employs a CDMA scheme, the amplitude associated with each independent CDMA carrier is digitally limited, thereby limiting the peak-to-average power ratio. This, in turn, is accomplished by measuring the instantaneous amplitude for the in-phase and quadrature signals that make up each CDMA carrier, deriving a maximum amplitude based on the instantaneous amplitude measurements, and then deriving one or more scaling factors based, in-part, on maximum amplitude. The one or more scaling factors are then applied to the in-phase and quadrature signals, which are subsequently filtered, combined and modulated by a corresponding CDMA carrier frequency.
