摘要： A method for decoding maximum posterior probability, comprising (1) calculating the N-th backward probability to the first backward probability in the reverse direction, discretely storing the ms-th backward probability, the m(s-1)-th backward probability, ..., and the m2-th backward probability, continuously storing the m1-th to first backward probabilities, calculating the first forward probability, finding the first decoding result by using the first forward probability and stored first backward probability, and similarly finding the second to m1-th decoding results, (2) then, calculating and storing the stored m2-th backward probability to the (m1+1)-th backward probability, calculating the (m1+1)-th forward probability, finding the (m1+1)-th decoding result by using the (m1+1)-th forward probability and the stored (m1+1)-th backward probability, and similarly finding the (m1+2)-th to m2-th decoding results, and (3) similarly finding the (m2+1)-th to N-th decoding results.

摘要： A scheduling process handles a plurality of communication services in a collective manner, thus making a radio communications system more operable. A pilot signal sender (10a) sends pilot signals with carrier frequencies each corresponding to an N (N‰¥1) different communication services. A scheduler (15) collects Nxn instances of propagation environment data from n (n‰¥1) terminal devices and selects terminal devices and communication services therefor by assigning terminal devices having a better propagation environment to the plurality of different communication services in a collective manner. The pilot signals are used by a propagation environment data sender (20a) to measure and report a propagation environment of each carrier frequency. A communication function configurer (26) automatically sets up a communication function to adapt to the communication service that the base station (10) has assigned.

摘要： A communications system for communications by a multicarrier transmission mode between a plurality of communications apparatuses (10, 20) wherein an overall frequency band assigned to the communications system is divided into a plurality of frequency bands each having a constant bandwidth (for example band 1 to band 4) and a specific band (for example band 1) among these divided bands is used to transmit used frequency band information and thereby determine the assignment of the remaining bands (band 2 to band 4) to be used between said communications apparatuses. Here, the specific band is defined as a main band for transmitting control channel information including said used frequency band information and also data channel information. The main band may also be added with an extension band for transmitting further data channel information. Further, the main band and extension band can be changed in the frequency band used along with time or can be changed in the number thereof. Both of the main band and the extension bands are preferably used by multiplexing by some of communications apparatuses.

摘要： A device such as a turbo decoder that requires interleaving and de-interleaving comprises a memory section (5) and a memory control section (12) for changing the sequence in which data are written into or read from the memory section (5) depending on whether to perform interleaving or de-interleaving. The single memory section (5) functions as both an interleaver and a de-interleaver, resulting in a reduction in the cost and size of the device.
