Abstract
In an adaptive array terminal, at least one of two antennas (ANT#1, ANT#2) is a movable antenna. A display unit of the terminal displays reception levels of, or level difference between, the two antennas. Thus, it becomes possible for a user to adjust an angle of the antenna such that reception levels of the two antennas come closer to the same level. Alternatively, control unit of the terminal automatically adjusts the antenna angle so that reception level difference between the two antennas becomes not higher than a prescribed value.
Claims19
An adaptive array wireless terminal apparatus having a plurality of antennas, comprising:
- a determining unit configured to determine reception levels of signals of a plurality of streams received by respective ones of said plurality of antennas;
- a display unit configured to display said determined reception levels of signals of said plurality of streams;
- and
- a reception level adjusting unit configured to be manually operated by a user and configured to adjust the reception levels of signals of said plurality of streams so that a difference in a reception signal level between said plurality of antennas before adaptive array processing can be reduced for improving the reception characteristics of the adaptive array processing.
A method of displaying a reception level in an adaptive array wireless terminal apparatus having a plurality of antennas and a reception level adjusting unit, comprising the steps of:
- determining reception levels of signals of a plurality of streams received by respective ones of said plurality of antennas;
- displaying said determined reception levels of signals of said plurality of streams;
- and
- adjusting the reception levels of signals of said plurality of streams in response to manual operation of said reception level adjusting unit so that a difference in a reception signal level between said plurality of antennas before adaptive array processing can be reduced for improving the reception characteristics of the adaptive array processing.
A digital signal processor configured to execute a reception level display program stored in a memory for an adaptive array wireless terminal apparatus having a plurality of antennas and a reception level adjusting unit, causing the digital signal processor, when executing said program, to perform the steps of:
- determining reception levels of signals of a plurality of streams received by respective ones of said plurality of antennas;
- and
- displaying said determined reception levels of signals of said plurality of streams;
- and
- adjusting the reception levels of signals of said plurality of streams in response to manual operation of said reception level adjusting unit so that a difference in a reception signal level between said plurality of antennas before adaptive array processing can be reduced for improving the reception characteristics of the adaptive array processing.
A digital signal processor, configured to execute a reception level display program stored in a memory for an adaptive array wireless terminal apparatus having a plurality of antennas, causing the digital signal processor, when executing said program, to perform the steps of:
- determining reception levels of signals of a plurality of streams received by respective ones of said plurality of antennas;
- and
- displaying said determined reception levels of signals of said plurality of streams,
- wherein
- in said display step, any of said numerical value indicative of the reception level of each of the signals of said plurality of streams, said difference value between each of the reception levels and said degree of magnitude of the difference value is selectively displayed as display contents;
- said program causing the digital signal processor to further perform the step of periodically and successively switching the display contents to be displayed in said display step.
A method of displaying a reception level in an adaptive array wireless terminal apparatus having a plurality of antennas, comprising the steps of:
- determining reception levels of signals of a plurality of streams received by respective ones of said plurality of antennas;
- and
- displaying said determined reception levels of signals of said plurality of streams,
- wherein said displaying step comprises:
- turning on a light emitting unit on a display without any flickering when differences between the determined reception levels of signals of the plurality of streams are all within a first difference value;
- turning on the light emitting unit on the display with a flickering rate greater than zero but less than a predetermined flickering rate, when the difference between the determined reception levels of signals of at least two of the plurality of streams is greater than the first difference value but less than a second difference value that is greater than the first difference value;
- and
- turning on the light emitting unit on the display with a flickering rate greater than the predetermined flickering rate, when the difference between the determined reception levels of signals of at least two of the plurality of streams is greater than the second difference value.
