摘要： Disclosed are a method and apparatus for generating a controlled spectrum of modulated energy. A single data stream is splintered into substreams. Each substream is used to modulate a portion of the modulated spectrum. Each substream is transformed into a numerical phase and amplitude representation of a portion of the spectrum to be modulated. The combined numerical representations are then converted to a time-domain representation and filtered to eliminate undesired side-lobes.

摘要： A synchronized frequency hopping method and apparatus for use in a cellular communication system where the cellular communication systems has a plurality of cells and a plurality of frequencies available to be assigned to the cells. At predetermined times, cells in the system synchronously change or hop to a new frequency. The new frequency to which a cell hops to may be a function of the present frequency the cell is assigned. In addition, synchronized frequency hopping may occur at predetermined intervals and the pattern of hopping may periodically repeat. This technique limits the period of time a non-system source of interference may impair communications in any cell since the cell hops to different frequencies periodically.

摘要： A method and apparatus for using multiple code rates for forward error correction in a cellular digital data radio communication system. Each base station broadcasts a quantity called the power product (PP), which is equal to the base station transmit power, P.sub.BT, multiplied by the power level received at the base station, P.sub.BR. For a mobile unit to determine its appropriate transmit power, P.sub.MT, requires measuring the power received, P.sub.MR, at the mobile unit and performing the following calculation: P.sub.MT ==PP/P.sub.MR. When channel path loss is large, it is possible that the power control calculation will return a value greater than the maximum transmit power capability of the mobile unit. In such a case, the mobile unit selects a lower code rate. Base station receiver sensitivity improves as the code rate decreases, so the result is similar to increasing the transmitter power. In the preferred embodiment, the invention uses 3 different code rates. In most cases, the code rate used is rate 2/3, but when a mobile unit determines that it needs more transmit power than it is capable of providing, the code rate is changed to 1/2, and in severe cases the code rate is changed to 1/3. Other features are that mobile unit code rate selection can be based on the quantity of data to be transmitted, and a base station can determine the code rate used by a mobile unit by attempting to decode all code rates and choosing the best result.
摘要翻译：一种在蜂窝数字无线电通信系统中使用多码率进行前向纠错的方法和装置。每个基站广播称为功率产品（PP）的数量，其等于基站发射功率PBT乘以在基站接收的功率电平PBR。要移动单元确定其适当的发射功率，PMT需要测量移动单元接收的功率PMR，并执行以下计算：PMT = PP / PMR。当通道路径损耗大时，功率控制计算可能返回大于移动单元的最大发射功率能力的值。在这种情况下，移动单元选择较低的码率。基站接收机灵敏度随码率的降低而提高，结果与增加发射机功率相似。在优选实施例中，本发明使用3种不同的代码率。在大多数情况下，所使用的码率是速率2/3，但是当移动单元确定需要比能够提供的更多的发射功率时，码率被改变为1/2，并且在严重的情况下，码率改为1/3。其他特征是移动单元码率选择可以基于要发送的数据量，并且基站可以通过尝试解码所有码率并选择最佳结果来确定移动单元使用的码率。

摘要： Provided is a frame structure for filtered OFDM signaling, wherein once every frame a central controller passes redundant broadcast data for a short time (e.g. 16 symbol times) over all frequencies in use. This broadcast, called a beacon, may carry control information, frame structure information, and other data. The rest of the frame is divided into other assignments, including broadband redundantly coded channels for broadcast, ALOHA contention access, or point-to-point transmissions, and including traffic channels that may use only some of the assigned frequencies intended primarily for point-to-point access. This allows a mix of TDMA and FDMA point-to-point and broadband access. This system may be controlled by a central coordinator, which issues reservations. This system allows devices on a frequency-selective channel to communicate with scheduled operations.
