摘要： An entire radio transceiver can be completely integrated into one IC chip. In order to integrate the IF filters on the chip, a heterodyne architecture with a low IF is used. A single, directly modulated VCO is used for both up-conversion during transmission, and down-conversion during reception. Bond-wires are used as resonators in the oscillator tank for the VCO. A TDD scheme is used in the air interface to eliminate cross-talk or leakage. A Gaussian-shaped binary FSK modulation scheme is used to provide a number of other implementation advantages.

摘要： Transmission power in a frequency-hopping radio system that transmits packets from a sending radio unit to a receiving radio unit, wherein each packet includes an address designating the receiving radio unit, is controlled by measuring received signal strength of packets whose addresses were successfully received in the receiving radio unit, regardless of whether other portions of the respective packets were successfully received. An average signal strength value is generated from the received signal strength measurements. The mathematical difference between the average signal strength value and a target value associated with the receiving radio unit is then determined and used as a basis for deciding whether to send a power control message from the receiving radio unit to the sending radio unit. In order to provide a hysteresis in the power control process, a power control message is sent from the receiving radio unit to the sending radio unit if the mathematical difference is greater than a first decision boundary, or if the mathematical difference is less than a second decision boundary. The power control message may itself include the mathematical difference which, when received by the sending radio unit, is used as a basis for determining a transmission power level adjustment amount. The target value, against which the average signal strength value is compared, may be based on the receiver sensitivity adjusted to account for implementation losses and other inaccuracies.
摘要翻译：在发射无线电单元向接收无线电单元发送分组的跳频无线电系统中的发射功率，其中每个分组包括指定接收无线电单元的地址，通过测量其地址被成功接收的分组的接收信号强度来控制接收无线电单元，而不管各个分组的其他部分是否被成功接收。从接收信号强度测量值产生平均信号强度值。然后确定平均信号强度值和与接收无线电单元相关联的目标值之间的数学差异，并将其用作决定是否从接收无线电单元向发送无线电单元发送功率控制消息的基础。为了在功率控制过程中提供迟滞，如果数学差异大于第一判定边界，则功率控制消息从接收无线电单元发送到发送无线电单元，或者如果数学差小于第二判定边界决定边界。功率控制消息本身可以包括当由发送无线电单元接收时被用作确定发送功率电平调整量的基础的数学差异。平均信号强度值与之对比的目标值可以基于被调整以考虑实施损失和其他不准确性的接收机灵敏度。
