IPC: G05D3/12
Filed: 1978-09-08
Abstract: PURPOSE: To decentralize loads evenly by allowing a job schedule processor to register a request of a job to be executed to a queue on a common memory and each processor to receive and execute this job request.  
     CONSTITUTION: Assigned job schedule processor PC210 links at a certain point in time a job request to be executed to job request queue 310 on common memory 300. Other PCs 220 and 230 fetch and execute sequentially jobs from queue 310 and then move to next job requests. On finishing a scheduled job, PC 210 also fetches and executes a job request from queue 310 as well as other PCs 220 and 230. In this way, after each job is finished, each PC fetches a next job request at random, so that loads will be decentralized on the whole.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To compensate distortion changing without interruption with a simple configuration by giving a weight to received multi-symbol signals, combining them, processing them and generating sequentially a weight coefficient with respect to a symbol according to a conjugate gradient algorithm. SOLUTION: A modulator 40a of a transmitter 32 modulates a multi-symbol digital signal St and a pulse shaping filter 42a provides an output of a signal subject to root raised cosine pulse shaping. A base band(PB)/RF converter 44a converts the signal into an RF wave and it is sent via a direct propagation path 38a and lots of different reflection wave propagation lines 38b. An RF/BB converter 44b of a mobile receiver 36 converts an RF signal received by an antenna 46 into a BB signal, and a matching filter 42b generates a signal Xt while matching the operation of a filter 42a. The signal Xt is processed by a demodulator 40a, which provides an output of a digital signal Ut. Thus, the system is adapted at a high speed with a simple configuration and distortion of a reception signal changing without interruption is compensated.
