摘要： A base station transmits, in addition to a pilot channel, signals which are multiplexed with pilot symbols inserted in the respective signals in communication channels. As the transmission of the pilot channel as a reference signal for coherent detection is unnecessary with high power so as to attain high reliability, the pilot channel can be transmitted with low power by means of weight in comparison with the communication channel, so that interference with the communication channel of any other station is reduced. Moreover, accurate coherent detection can be made from the pilot symbol inserted in the communication channel on the mobile station side.

摘要： The invention intends to improve an error correcting capability in an error correction encoding/decoding apparatus. On the encoding side, after a fixed bit of 0 or 1 was inserted into information signal series to be convolutional correction encoded, the resultant information signal series is convolutionally encoded. On the decoding side, by using the fixed bit inserting position stored in a fixed bit inserting position storing circuit, the information signal series is decoded while limiting the state transition corresponding to the bit position at which the information bit is the fixed bit into only one kind that is decided by the value of the fixed bit.

摘要： The invention provides greater error correction capability in an error correction encoding/decoding system of a digital mobile telephone or so forth. In a viterbi decoding system at a receiver side, a branch metric is calculated and stored without selecting a path with respect to a plurality of branches corresponding to a parameter having a correlation between frames. Also, by utilizing a separately stored parameter value in a previous frame, a transition probability of the parameter value in the current frame is obtained, a metric value of a path is converted and added to an accumulated path metric value up to the previous branch, a comparison of the metric values at various states is performed to select the path having higher likelihood to perform decoding by maximum likelihood decoding.

摘要： The CM controller 101 outputs times at which signals are sent to various communication terminal apparatuses in a compressed mode based on information on the compressed mode sent from a host station such as a control station apparatus to the scheduler 102, coder 105 and modulator 106. The scheduler 102 decides times (order) at which packet data is sent to the respective communication terminal apparatuses based on priority information such as channel conditions and times at which signals are sent in the compressed mode and outputs schedule information indicating the times for creating this packet data to the switch circuit 104. The switch circuit 104 outputs the packet data to be sent to the communication terminal apparatuses sequentially to the coder 105 according to the schedule created by the scheduler 102.

摘要： A radio communication apparatus, base station apparatus and communication terminal apparatus capable of predicting an accurate transmission rate before starting data communications to know download time and the like. In the apparatus, a packet CH demodulation section (103) demodulates received packet data. A pilot CH demodulation section (104) demodulates a received signal of a pilot channel. A reception state measuring section (105) measures the SIR from the received signal of the pilot channel. A transmission rate candidate selecting section (106) stores a calculation expression that associates CQI with SIR, and selects CQI by the calculation expression using the measured SIR. A transmission rate predicting section (108) averages selected CQI for a predetermined time to output a transmission rate prediction value. A transmission rate prediction control section (110) outputs information of the transmission rate prediction value to a display section (111) when detecting a key input. The display section (111) displays the transmission rate prediction value on a liquid crystal screen.
