Embodiment Construction

[0024] FIG. 1 illustrates a transmitting and receiving device used, for example, in a mobile station in a mobile wireless network. The device has a baseband component 1 which is connected to a radio frequency component 3 via a digital interface 2 . The radio frequency component 3 has a power amplifier 4 on the output side, which is connected to an antenna 5 .

[0025] The baseband unit 1 has a digital signal processor DSP for processing payload data, like a microprocessor μC, which is associated with the entire transmitting and receiving device, processing structured data and providing sequence control.

[0026] The baseband component 1 performs a baseband process on transmitted data and received data. This includes signal processing steps at the information bit level (e.g. GSM) or at the chip level (e.g. UMTS), such as transport blocks, error protection coding, bit rate matching, channel coding (convolutional or turbo coding), insertion, transport stream multiplexing , code...

Abstract

A transmitting / receiving arrangement has a baseband component (1) and a radio-frequency component (3) that are connected via an interface (2). The interface has a first differential unidirectional data link (14) for transmission of digital transmission data from the baseband component (1) to the radio-frequency component (3), and a second differential unidirectional data link (12) for transmission of digital received data, which is converted to baseband in the radio-frequency component (3) from the radio-frequency component (3) to the baseband component (1).

Description

technical field [0001] The present invention relates to a transmission and reception device of a wireless device with a baseband unit and a radio frequency unit, wherein the baseband unit and the radio frequency unit are connected via an interface to exchange payload data in the direction of transmission and reception. The invention also relates to a method for transmission between the baseband component and the radio frequency component of the wireless device designed in this way. Background technique [0002] In the mobile station, adjusters and demodulators are used in the transmitting and receiving devices to adjust a carrier wave and receive data according to the transmitted data, and to demodulate the corresponding modes according to standardized adjustment and demodulation methods received data. Known adjustment and demodulation methods, such as GSM (Global System for Mobile Communications), EDGE (Enhanced Data Speed ​​for GSM Evolution), TIA-EIA 136 (Electrical Comm...
