Abstract: A DS-CDMA transmission method capable of improving the accuracy of channel estimation using pilot symbols by eliminating cross-correlation between pilot symbols inserted into code channels in CDMA multiplexing carrying out fast signal transmission. In each frame assembler, the pilot symbols, which are used for channel estimation for coherent detection, are inserted into coded information data on code channels at fixed intervals, and then the data is modulated by the modulator. The modulated data symbols in each code channel from the modulator are spread by the spreading modulator, the pilot symbols are spread using a spreading code, whereas the information symbols are spread using different spreading codes assigned to respective code channels. The spread signals of the code channels are summed up by the adder to be transmitted.

Abstract: L'invention concerne des unités logiques, et un procédé correspondant, de fourniture de services dans un système de communication mobile. Dans ce système de communication mobile, un certain nombre d'appels sont traités pour le compte d'un utilisateur. Ces appels peuvent avoir différentes capacités de support. Au cas où un appel supplémentaire doté de la même capacité de support demanderait à être établi, un autre appel parallèle peut être établi ou un appel peut être mis en garde, déconnecté, ou mis en mode attente. En outre, les capacités de support du nombre n+1 d'appels sont vérifiées de manière à déterminer si l'un des appels n possède la même capacité de support. Ensuite, on vérifie si l'un des appels satisfait les exigences de support et peut être mis en garde. Si tous les appels satisfont les exigences, l'appel est mis en garde et l'appel suivant est mis en garde. Outre ces services, l'invention porte également sur la conférence téléphonique et le envoi automatique d'appels.

Title: Forward error correction on multiplexed cdma channels enabling high performance coding
Inventor: FERGUSON DENNIS D
IPC: H04L47/43
Filed: 2000-02-23
Abstract: A protocol for optimizing the use of coded transmissions such as over wireless links. In this technique, interframes are first split into segments selected to be an optimum size according to transmission characteristics of the radio channel. Segments are assigned a position identifier and redundancy check sum. Segments are then assembled into blocks and a forward error correction algorithm is applied to the block to generate redundancy bits. The FEC block is then split up among available communication channels and forwarded to the receiver. The inverse process is applied at the receiver. Using this scheme, only segments containing erroneous data need to be resent. A large block size required for high performance forward error correction may therefore be used while at the same time minimizing latencies associated with the need to resend entire blocks when errors cannot be recovered.
