Title: Code error detection system
Inventor: NODA SEIICHI
IPC: H04L27/00
Filed: 1989-12-29
Abstract: PURPOSE:To simplify the circuit for code error detection by applying decoding calculation of only one of in-phase and orthogonal signals so as to detect a code error in a relay station. CONSTITUTION:An nXt degree arithmetic circuit 23 uses an nXt degree generation polynomial g(x) to one of data signals D3, D4, in this case, a synchronous data signal D3 to apply decoding calculation, generates an arithmetic result signal S1 and sends it to an error detection circuit 25. The error detection circuit 25 detects a code error based on the arithmetic result signal S1 and outputs an error detection signal SE. A modulation circuit 22 uses the demodulated data signals D3, D4 to apply orthogonal amplitude modulation and sends the result to a reception terminal station 30. The arithmetic circuit 23 is provided only either of the in-phase and orthogonal data signals to apply decoding calculation in a relay station 20 in this way and the symbol error rate of the in-phase and orthogonal data signals in the orthogonal amplitude modulation system is equal to each other. Thus, a code error is detected by excellent accuracy.

IPC: H01L29/73
Filed: 1991-12-26
Abstract: PURPOSE:To manufacture a semiconductor device of high speed and high performance, by forming a recess on the side surface of a first conductor film turning to a base electrode. CONSTITUTION:An SiGe layer 12 composed of SiGe of about 100nm in thickness to which high concentration (about 5X10<18>cm<-3>) of boron is added is selectively formed by epitaxial growth, only on a poly silicon film 6 exposed on the side surface of an aperture 9 and on an epitaxial layer 11 exposed on the bottom surface of the aperture 9. Since the average distance between the poly silicon layer 6 and the silicon epitaxial layer 11 is long as compared with that of the conventional bipolar transistor, an outer base diffusion layer becomes hard to be formed. Thereby the collector base junction capacitance is remarkably reduced, so that the cutoff frequency of a transistor can be very much improved.
