  • Patent number: 7333567
    Abstract: A digital detector processes at least one received digital signal to generate a squared signal, encodes the squared signal, applies first and second portions of the encoded signal to a multiplier and a look-up element, respectively, and processes outputs of the multiplier and look-up element to generate a detector output signal representative of a power level of the received digital signal. In an illustrative embodiment, the digital detector is configured so as to exhibit a waveform dependence substantially the same as that of an analog logarithmic amplifier detector. The digital detector and analog logarithmic amplifier detector are utilizable in a closed-loop gain control arrangement for providing a desired gain for a signal path of a base station transmitter in a wireless communication system.

  • Patent number: 7062242
    Abstract: A DPRAM is placed in the RF path before the digital to analog converter, to provide dynamic path gain compensation to the digital signal prior to conversion to an analog signal. The DPRAM stores corrections to the signal to compensate for amplitude losses in the signal arising from heat and non-linearities. The DPRAM has two sets of identical addresses. A logic switch, alternately directs an input signal to one of the two sets of addresses. Pre-calculated signal values which compensate for path gain are stored in one of the two sets of addresses in the DPRAM. The signal input to the DPRAM is directed to the other block. The value of the signal input to the DPRAM will determine the address to which the new value can be found. It is this new value which is actually input to the DAC and from which an analog signal is created.

  • Publication number: 20020120595
    Abstract: An apparatus includes a processor, a memory coupled to the processor, and a download program stored in the memory. The processor operates according to the download program to create a link list at the beginning of a downloadable file. The link list describes the number and size of the memory images that are being downloaded making downloading more flexible. Then the processor operates according to the download program to download the file to a base station. This reduces the amount of application download time and allows for incremental updates of separate pieces of application firmware.
