Radio receivers and methods for receiving modulated with two types of modulation data bursts

Radio receiver (10) for receiving a light emitted from a transmitter data burst (1), wherein the data burst (1) sent a first portion (2), which was the transmitter side is modulated with a first modulation method, and after the first section (2), second portion (4, 5), which has been modulated on the transmitter side with a second modulation scheme, comprising, with - a first receive path (12) for processing the first portion (2), and - a second receive path (13) for processing the second portion (4, 5), characterized, - that the radio receiver comprises a first common receive path (134), which is both a component of the first receive path (12) and the second receive path (13) and having a unit (134) for timing recovery, wherein the unit (134) for clock recovery from the first receive path (12) output digitized receive signals and output from a second receive path (13) received signal bit stream obtained and determined from the supplied data and outputs the sampling phase.
