摘要： A multi-carrier transmitter, wherein a DET (28) finds the locations where clip distortions occur when a received multi-carrier signal is converted into a digital signal and the number of clip distortions by means of an A/D (22) from the output of the A/D (22) while regarding the clip distortions as additional noise. Then substractors (26, 27) find the difference values between the information symbols at both ends of a received block signal on a frequency axis outputted from a DFT (24) and a known zero symbol, and a CAN (25) estimates the magnitudes of the clip distortions from the difference values and the locations and number of clip distortions and eliminates the clip distortions.

摘要： On the transmission side, a multiplexing section estimates the quantities of information from signal processing sections, determines multiplexing codes based on the quantities of information, takes the parity of a determined first multiplexing code, and uses the parity as a second multiplexing code. The multiplexing section then generates two headers (H 1 ) and (H2) by adding a CRC to each multiplexing code, fetches information data of each medium in accordance with the multiplexing codes, incorporates the data in a packet together with the two headers (H1) and (H2) and outputs the packet. On the reception side, error correction decoding is performed by using the header (H2) when the error correction of the header (H1) is impossible, or by using both headers (H1) and (H2) when the error correction of the header (H2) is also impossible.

摘要： A multiplexing unit on the transmitting side estimates information amounts supplied from respective signal processing units, determines a multiplex code on the basis of respective information amounts, derives a parity of the first determined multiplex code to form a second multiplex code, adds a CRC to each of the multiplex codes to generate two headers H1 and H2, takes out information data of respective media according to the multiplex codes, incorporates the information data into a packet together with the two headers H1 and H2, and outputs the packet. If error correction of H1 is impossible on the receiving side, error correction decoding is conducted by using the header H2. If error correction of H2 is also impossible, error correction decoding is conducted collectively for H1 and H2.

摘要： Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved. Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line. In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected. Thus, high through-put characteristic and statistic multiplexing effect intrinsic to the ATM method can be accomplished even in the extension line interface.
