摘要： Electronic devices may be provided that contain wireless communications circuitry capable of supporting time division multiple access. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. Signal strength measurements may be gathered using the antennas and corresponding signal strength difference measurements may be computed to reflect which of the antennas is exhibiting superior performance. The signal strength measurements may be made by measuring receive power levels in a beacon channel during idle time slots while toggling its antennas in and out of use or by detecting for the presence of non-silent traffic channel frames or silence indicator description frames and measuring corresponding receive power levels while toggling its antennas in and out of use. Beacon-channel-based measurements and non-silent-frame-based measurements may be used for electronic devices with receive diversity by simultaneously receiving frames of interest using each of its antennas and making corresponding measurements in parallel.

摘要： Method for receiving and transmitting data packets in a wireless communication device comprising M transceivers (with M≥2), N antennae (with N>M), each connectable with at least one of the M transceivers, and a switching system adapted to connect each of said M transceivers to only one of said N antennae at a time. The wireless communication device is operated according to a normal mode and a test mode. In the normal mode, the transceivers of the device are connected to a subset of antennae. The link quality is also evaluated, such that the used antennae can be subdivided into subsets according to the evaluated quality. In the test mode, a subset of the transceivers remains connected to the corresponding subset of antennae which gave the best link quality, and the remaining part of the transceivers is connected to a corresponding number of antennae, at least in part different from those which gave the worse quality, in such a manner searching for an improved configuration.

摘要： An apparatus and method for improving antenna diversity in a receiver of a broadband wireless communication system using multiple antennas are provided. The receiver with the diversity apparatus uses a structure of multiple analog front ends, a structure for measuring antenna-by-antenna reception power values/Carrier-to-Interference plus Noise Ratios (CINRs) after Fast Fourier Transform (FFT) using a single analog front end, and a structure based on a single analog front end for measuring antenna-by-antenna reception power values after Analog-to-Digital (A/D) conversion without use of FFT. When a receive antenna is selected, the measured reception power values/CINRs are used. In a system for transmitting pilot signals with preamble data in a regular pattern, the receiver can have improved performance through a suitable frequency modulation process and can be implemented at low cost, as compared with that of the conventional antenna selection diversity.

摘要： An antenna diversity receiver has a low-IF receiving mode and a diversity selection mode, and a switch arrangement for coupling one of the antennas to the IF channels when in the receiving mode, and coupling each of the channels to a different one of the antennas in the selection mode. A diversity controller compares qualities of signals received simultaneously from the different antennas during the selection mode, and controls the switch arrangement in the receiving mode, to use the better antenna. The quality measurement is carried out during reception of a carrier before a preamble to a desired signal is received, so that there is more time to obtain a better signal quality measurement and to enable better averaging over time. The channels have a polyphase filter with switchable cross coupling between the channels, so that it acts as two independent low pass filters in the selection mode.

摘要： In assessing the signal quality of the preamble signal of a received digital signal, time intervals between transitions between the high and low levels of the preamble signal are determined and compared to a predetermined reference time interval. For each determined time interval, a value indicative of the difference between the determined time interval and the predetermined reference time interval is calculated, and for the determined time intervals, a sum of the indicative values is formed and used as a quality indicator of frequency accuracy of the preamble signal. Alternatively, the sum of the absolute values of the indicative values is formed and used as a quality indicator of phase accuracy of the preamble signal, or a weighted sum of the two is used as a total quality indicator of the signal quality of the received signal.

摘要： A method whereby a mobile terminal (MT) operating in a wireless local area network (WLAN), for example HiperLAN2, can effect antenna diversity. The mobile terminal which has at least two antennas (24,26) monitors downlink fields in successive time frames in a time division radio transmission for indications of when downlink message signals are to be sent to mobile terminals other than the one effecting the monitoring and determines from the indications when there will be in the time frame a time period of sufficient duration for the mobile terminal to effect antenna diversity measurements. The mobile terminal measures in the selected time period the quality of signal reception by each of the at least two antennas and selects the one of the said at least two antennas providing the better (or best) quality of signal reception.
