摘要： 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.

摘要： The present invention includes a time-division-multiple-access (TDMA) communication system having a base station and at least one mobile station, each transmitting and receiving an analog radio-frequency signal carrying digitally coded speech. The speech is encoded using a vocoder which samples a voice signal at variable encoding rates. During periods when the radio-frequency channel is experiencing high levels of channel interference, the encoded voice channel having a lower encoding rate is chosen. This low-rate encoded voice is combined with the high degree of channel coding necessary to ensure reliable transmission. When the radio-frequency channel is experiencing low levels of channel interference, less channel coding is necessary and the vocoder having a higher encoding rate is used. The high-rate encoded voice is combined with the lower degree of channel coding necessary to ensure reliable transmission. The appropriate levels of channel coding necessary for reliable transmission are determined by various channel metrics, such as frame erase rate and bit error rate. The determination of the appropriate vocoder rate and level of channel coding for both the uplink and downlink may be determined centrally at the base station, with the vocoder rate and level of channel coding for the uplink being relayed to the mobile station. Alternatively, the appropriate vocoder rate and level of channel coding for the downlink may be determined by the mobile station, and the appropriate vocoder rate and level of channel coding for the uplink may be determined by the base station.

摘要： An emulation controller (12) located externally of an integrated circuit (14) can be provided with timing information indicative of operation of an internal clock of the integrated circuit that drives internal data processing activity of the integrated circuit. In response to each cycle of the internal clock, a corresponding digital bit is produced to represent the internal clock cycle, and the digital bits are output to the emulation controller at an output clock rate that differs from the clock rate of the internal clock.
