Wong Lung Hsiang;

A method of optimizing delivery of computer media over a network of computers involves creating an annotation record for each item of computer media. Within the annotation record at least some of the following classes of information are included: (i) an id of the computer on which the media item was created or introduced to the network; (ii) ids of 1 or more computers on which a copy of the media item is presently located; (iii) an id list of computers which have established a computer link to the media item; (iv) an id list of computer users who have personal software assistants which have established a computer link to the media item; (v) an indication enabling version control of the media item; and (iv) 1 or more indications as to the subject matter of the media item. Whenever a media item is updated or deleted, the corresponding annotation record is also updated and a notification record is forwarded to each computer or a personal software assistant of each computer user on the network which has a computer link to the media item.

A Joint Channel & Information Sequence Estimation Technique

Alexander Paul D.;

A method of channel estimation comprising the steps of: receiving a signal consisting of a superposition of signals from a plurality of channels; from the signal constructing an observation sequence estimate which models the contributions to the signal from each channel; constructing from the observation sequence estimate an estimate modeling the behavior of each channel, the estimate being dependent on a number of parameters; computing at least one contribution to the observation sequence estimate for each channel which is not dependent on at least one of the parameters, the contributions being functions of some or all of the estimates modeling the behavior of the other channels; and for each of the contributions removing the contribution from the observation sequence estimate to form a new modeling the behavior of each channel.

Receiving Device & Channel Estimator for CDMA Communication System

Sugimoto Hiroki,
Oyama Takashi,
Matsumoto Yoshihiro,
Sun Sumei,
Cheah Kok Leong;

At a base station, a CDMA received signal coming in through an antenna  isfed to a radio frequency unit (RFU) or high frequency unit. The RFU  demodulatesa basebandsignal BB from a signal RF & delivers the signal BB to an A/D converter. The resulting digital signal output from the A/D is input to a hybrid interference canceller (HIC) as a received signal Rx Data. The HIC divides users into 2 groups and assign one combination of a parallel interference canceller and a serial interference canceller to each group. The HIC cancels interference contained in the received signal Rx Data for thereby estimating symbols particular to a plurality of users.
