Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.

A time division multiplexer is provided for multiplexing data from a plurality of channels. The TDM system generally comprises a high speed time division multiplexed data bus (106), a synchronizing bus (104), a plurality of channel cards (112-116) coupled between the data channels and the data bus with each channel card having its own processor and memory, and a communication manager (120) which is also coupled to the digital bus, and includes a (micro)processor (130). The processor of the SCM determines the frame for the system and initially forwards the frame information to each of the channel cards during predetermined time slots of the high speed data bus. The channel cards are synchronized by the SCM (120) via the synchronization bus (104), and the channel cards use the synchronization information and framing information in order to appropriately place data on and take data off the high speed bus without the use of an address bus.

The synchronizing signal (SYNC1) controls a coding timing of the coder and a speed conversion timing of the speed converting circuit.
