Title: System including mobile radio station and base radio station
Inventor: KANADA YOSHIHISA
IPC: H04L12/28
Filed: 1995-10-12
Abstract: A mobile station which wants to start communication with a base station transmits a communication slot assignment request to the base station at a sufficiently low transmission speed at which no transversal filter is required. The base station assigns a communication slot and transmits the information regarding the communication slot assignment to the mobile station at a sufficiently low transmission speed at which no transversal filter is required. Upon receiving the information, the mobile station transmits a training sequence to the base station at a high speed by using the assigned communication slot. The base station calculates the optimum tap coefficient in a transversal filter from the training sequence held by the base station itself and from the actually received signals by means of an adaptive equalizing mechanism and transmits the optimum tap coefficient to the mobile station at a sufficiently low transmission speed at which no transversal filter is required. The base station sets the tap coefficient in the transversal filter and starts high-speed communication with the base station.
