摘要： A TDMA radio terminal comprises a transmitter portion and a receiver portion. A reference signal is launched in the transmitter portion while tuning the receiver portion. At the same tine, an internal delay counter is started. The counter counts clock pulses till the reference signal returns through the receiver portion. Letting this pulse count be Nd, a transmission wait time is Nt - Nd. Nt is a transmit timing at the antenna. The Nd counting operation may be triggered by a power on or a signal from a controller. Method for determining the transmission wait time in the production site is also disclosed.

摘要： The present invention improves quality of communication in a transmission and reception system, a transmission and reception device, and a method of transmission and reception, which utilize primarily a combination of punctured-convolution-coding and diversity. Degradation in likelihood of certain data is prevented by adopting the steps of (a) punctured-convolution-coding an identical information data 121 by using a plurality of different puncturing patterns 102a and 102b, (b) diversity-transmitting each of different series of punctured data obtained in step (a) as diversity branches, (c) depuncturing the series of punctured data individually in a receiving device 110 by using identical puncturing patterns 102a and 102b as used in the transmission side, and (d) compounding and convolution-decoding them thereafter.

摘要： QPSK modulated quadrature baseband signal generating section 301 generates a QPSK modulated quadrature baseband signal. 8PSK modulated quadrature baseband signal generating section 302 generates an 8PSK modulated quadrature baseband signal. Based on the modulation scheme determined information, in-phase component switching section 304 and quadrature component switching section 305 switch between the QPSK modulated quadrature baseband signal, 8PSK modulated quadrature baseband signal and pilot symbol to output to radio section 306. Radio section 306 performs the predetermined radio processing on the baseband signal to output a transmission signal. The transmission signal is amplified in power amplifier 307, and the amplified transmission signal is transmitted from transmission antenna 309. It is thereby possible to take into account both the improvement in the data transmission rate, and the benefit and convenience in terminals.

摘要： Convolver 104 calculates convolution integration between symbol number s given by calculation length determination section 118 of a series of known signals sequentially output from known signal storage section 103 and a series of signals corresponding to s symbols selected at symbol intervals from the reception signal series stored in shift register 102 and difference calculation section 105 calculates difference vectors corresponding to 1 symbol of the signal series subjected to convolution integration. Addition section 106 sequentially adds up the calculated difference vectors, calculates addition difference vectors in the same way by shifting the reception signal series 1 sample at a time, memory 107 stores the time of shifting in association with the addition difference vectors and detection section 108 detects parts that satisfy a specific condition from the vectors stored in memory 107.

摘要： A phase of a sampling clock provided from clock generating circuit 107 is switched periodically and alternately with a phase difference of 180 degrees, and during a period of each phase, timing estimating circuit 105 estimates a symbol timing. High-accuracy timing estimating circuit 109 selects an estimated result with higher reliability among symbol timing estimated results obtained in respective periods, thereby enabling estimation of the symbol timing with time resolution twice a sampling period. It is possible to decrease an operation frequency in an A/D conversion circuit even in a system requiring timing synchronization accuracy with high accuracy.

摘要： In a radio communication method whereby adaptive modulation is performed, a method is used whereby pilot symbol signal points are arranged in the in-phase-quadrature plane (IQ plane) so that the reception sensitivity of a receiving apparatus is made optimal in the respective modulation methods while maintaining the average transmission output power of the transmitting apparatus at a fixed level. By this means, it is possible to arrange pilot symbol signal points and improve the reception sensitivity characteristics of a receiving apparatus while maintaining the average transmission output power of the transmitting apparatus at a fixed level.
