摘要： It is a theme of the present invention to provide a diversity receiving device and a diversity receiving method capable of making a diversity start not to cause receiving errors and also improving a sensitivity. There is a difference in a jamming wave level that is allowed to get the same received quality between the diversity reception and the single branch reception, so that a gain improving effect equivalent to a diversity gain is expected by the diversity reception in contrast to the single branch reception. Therefore, a dynamic range of the jamming wave from a transmitting portion (105) of a second radio system in a radio terminal is set smaller in expectation of the improving effect of such jamming wave resistance, and then a transmission control signal (S117) is acquired from a transmission signal controlling portion (106). Thus, the diversity reception is started before a start of transmission, and diversity control is applied adaptively without deterioration of the received quality. With such arrangement, NF of the system is improved at the same time, and as a result a receiving sensitivity in both the single branch reception and the diversity reception can be improved.

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.
摘要翻译：本发明的目的是提供一种分集接收机和接收系统切换方法，该方法能够响应于人们的喜好和使用环境，根据切换条件来控制分集接收开始和停止。输入部分（109）允许用户总是选择并指定使用两个接收信道的分集接收模式，一直使用单个接收信道的单个接收模式，或者用于在分集接收和单个接收，并且控制部分（107）根据其他两种模式的模式选择信息确定在自动控制接收模式中使用的切换确定条件。如果分集接收选择频率大，则控制部将确定条件改变为用于将开关频率增加到分集接收的确定条件; 如果单个接收选择频率大，则控制部将确定条件改变为用于将开关频率增加到单个接收的确定条件。

摘要： The objective of the present invention is to provide a diversity receiver that detects differences in reception qualities for reception branches, and that controls the starting and halting of a diversity operation in accordance with the difference in the reception qualities, so that power saving is enabled and battery operating periods can be extended. A difference in reception levels (A, B) which are reception qualities for reception branches (13a, 13b), is employed to determine whether desired diversity effects are available or not. In a case wherein it is determined that desired diversity effects are not available, the diversity operation is halted and the supply of power to a reception branch that is not to be used is halted, and the combining operation is also halted.
