Title: Adaptive communication system
Inventor: OTAKE KOHEI
IPC: H04B1/7097
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To always obtain a high demodulation S/N while simplifying the configuration by correcting sequentially an inverse spread code so as to decrease an error between a demodulated output signal resulting from demodulating a received spread code with an inverse spread code and a recovered data output signal resulting from identifying and discriminating the demodulated output signal. SOLUTION: A receiver 10a gives an output signal series χ n, k outputted from a damp integration device 12 that receives a reception signal r(t) with a transmission line noise n(t) added thereto and output signal series χ n, k-1-χ n, k-L+1 generated by delaying sequentially the output signal series χ n, k at a delay device 13 to a variable coefficient device 14 and an inverse spread code control circuit 20. The inverse spread code control circuit 20 sets an initial value of an inverse spread code to be e.g. the same as that of a spread code and corrects inverse spread codes CR, L-1 -CR, O of the variable coefficient device 14 sequentially so that an error εn between a demodulated output signal yn and a covered data signal dn is decreased.  Thus, a complicated filter and complicated measurement of transmission line noise power are not required to obtain an optimum inverse spread code.
