摘要： It is a theme of the present invention to provide a diversity receiving device and a receiving scheme switching method, capable of attaining a power saving by executing a switching between a diversity reception and a single reception with high accuracy. A receiving scheme switching portion (112) switches a receiving mode between a single reception and a diversity reception based on a receiving scheme switching threshold, updates the receiving scheme switching threshold based on the receiving rate calculated by a receiving rate calculating portion (110), switches the receiving mode into the single reception in which respective ones of antennas (101, 105), radio demodulating portions (102, 106), and decoding portions (103, 107) are employed respectively and also turns OFF respective power supplies of the remaining antenna (101 or 105), the remaining radio demodulating portion (102 or 106), and the remaining decoding portion (103 or 107) when the received quality calculated by the received quality calculating portion (111) exceeds the receiving scheme switching threshold, and switches the receiving mode into the diversity reception in which the antennas, the radio demodulating portions, and the decoding portions are employed in both branches when the received quality is below the receiving scheme switching threshold.

摘要： An object of the invention is to provide a diversity receiver and a reception system switching method capable of controlling diversity reception start and stop according to the switch condition responsive to person's liking and the use environment.An input section (109) allows the user to select and specify any of a diversity reception mode using two reception channels at all times, a single reception mode using a single reception channel at all times, or an automatic control reception mode for switching between the diversity reception and the single reception in response to the reception state of each mode, and a control section (107) determines a switching determination condition used in the automatic control reception mode according to mode selection information of other two modes. If the diversity reception selection frequency is large, the control section changes the determination condition to a determination condition for increasing the switching frequency to the diversity reception; if the single reception selection frequency is large, the control section changes the determination condition to a determination condition for increasing the switching frequency to the single reception.
