Method and radio station for data transmission |
摘要 |
Data are transmitted through a radio interface in a GSM mobile radio system. The transmission side performs a continuous phase modulation of the transmission signals for the data to be transmitted. A bandwidth is used which is narrower than that used during a Gaussian minimum shift keying modulation with a modulation bandwidth BT equal to 0.3 so that the radio interface gives right of access on at least one channel with a reduced bandwidth. On the reception side, data detection is carried out without any discrimination between channels with different bandwidths. This enables substantially increased capacity of mobile radiotelephone networks and support for indoor and asymmetrical data transmission applications. |
