Title: Radio communication system
Inventor: MOULSLEY TIMOTHY JAMES
IPC: H04L1/00
Filed: 1998-06-17
Granted: 1999-11-21
Abstract: A method of operating a radio communication system uses multicarrier modulation for transmission of data between two or more stations. In the transmitter, multiple copies of parts of an input data stream can be generated by a repeater (204) to enable the application of variable degrees of diversity to different parts of the data. The diversity is applied by controlling the algorithm used by an interleaver (210) before the data is modulated (216) placed onto multiple carriers by an inverse fast Fourier transform (220) and transmitted (226). In the receiver, the multiple carriers are received (302), data is recovered from all the carriers by a fast Fourier transform (308) then demodulated (310). A de-interleaver (316) is controlled to use the same algorithm as the transmitter, copies of parts of the data stream are recombined (322) and an output bitstream is generated.

Title: Rake receiver architecture based on two-stage feedforward channel sounding
Inventor: HUANG JIA-CHI
IPC: H04B7/216
Filed: 1998-11-05
Granted: 2000-09-21
Abstract: A RAKE receiver plays a key role in a CDMA system. A novel RAKE receiver architecture based on two-stage feedforward channel sounding for a CDMA system is disclosed. The architecture is useful in two pilot transmission modes, a continuous pilot signal mode and a periodic pilot symbol mode. This architecture utilizes a two-stage channel sounding technique to estimate multipaths and contains a baseband sliding correlator, a channel response estimation subsystem and a correlator bank. At the first stage, we use the baseband sliding correlator to estimate the power delay profile of the multipath channel and obtain the code phases of M (e.g. 8) stronger paths. At the second stage, the channel response estimation subsystem first calculates the signal strengths and the carrier phase shifts for the selected M paths, and then selects L (e.g. 4) main paths out of the M paths according to the signal strengths. Finally, the correlator bank optimally combines the L main-path signals for data detection by utilizing the channel parameters including code phases, signal strengths and carrier phase shifts. The proposed architecture is simple in hardware complexity and suitable for VLSI implementation.

Title: Process for treating a material containing metal and organic matter
Inventor: NIEMINEN MATTI
IPC: F23G7/00
Filed: 1998-12-17
Granted: 2001-06-07
Abstract: The invention relates to a process for treating a raw material containing aluminium or a similar metal melting at a low temperature and organic matter, including metal separation. The invention is particularly intended for the treatment of liquid container rejects consisting of aluminium foil, polymer material and possible fibre residues in order to recover the aluminium and to utilise the organic matter as a fuel. In accordance with the invention, the raw material (5) is introduced in a bubbling fluidised bed (3), where the organic matter is gasified at a temperature higher than the melting point of the metal present. The gas removed from the fluidised bed and the entrained metal are subsequently cooled to a temperature below the melting point of metal by admixing a cooling medium such as water (6) in the gas flow. The solid metal particles are eventually separated from the gas e.g. with a cyclone (8) and the gas flow is possibly filtered (11) before combustion.

Title: Digital signature method for agent operation environment
Inventor: WU RUEI-MING
IPC: H04L9/00
Filed: 1999-01-22
Granted: 2001-03-11
Abstract: A digital signature method for agent operation environment can complete the signature operation of digital signature and sort the error responsibility for the resultant agent operation data on the remote server under a condition that the client computer needs not to transmit the secret key. The method utilizes the public key cryptography technology. After exchanging the public keys, the client computer generates the original data (M) and transmit same to the server, and let the server execute the agent operation (fi) and generate an agent operation result (N). Then, the server can use the secret key for signature operation to the (M, N, fi) data set and generate the server security data (SB). Thereafter, the N and SB are transmitted back to client computer. After the client computer received the data, the public key is used on the server for verification operation on SB. After verification, the client computer will use its secret key for signature operation on N and generate the client signature data (SN). Then, the secret key of client computer is used to conduct signature operation on the (M, N, fi, SB, SN) data set and generate the client security data (SA), Then, the SN and SA are transmitted to the server. After the server received the data, the public key of client computer is used for verification operation on SA. After verification, the SN is used as the digital signature data of client computer to N and is applied to the subsequent processes. If there is any operation error or disputation in the above processes, both parties can use the backup of SA and SB data for verification to clarify the responsibility.

Title: Apparatus and method to allow recording of voice messages based on call related information
Inventor: CANNON JOSEPH M
IPC: H04M1/57
Filed: 1999-03-09
Granted: 2000-09-01
Abstract: A voice messaging system includes pre-storage of a plurality of caller information in an authorized caller/call information directory. Each entry in the authorized caller/call information directory is associated with a respective variable indicating whether or not that caller may record a voice message. If the caller is not authorized to leave a voice message, the voice messaging system remains on-hook. Alternatively, the voice messaging system may go ""off-hook"" but play a special outgoing message to the unwanted caller. In an alternative mode of operation, the authorized caller/call information directory may contain the call information of those callers who the voice messaging system will not allow to leave a voice message. All other callers may leave a voice message. This allows a user to avoid the inconvenience of listening to voice messages from undesired parties such as from a telemarketer or a stalker.
