Abstract: A novel and improved system and method for assembling a single data stream from multiple instances of that data stream is described. Data transmitted from a cellular telephone subscriber unit (100) is received by a set of base transceiver stations (102). Each base transceiver station performs various error detection procedures on segments of the data referred to as frames (300). These error detection procedures may include CRC check sum verification, Yamamoto metric calculation, re-encoded signal error rate calculation, or a combination thereof. The results of these error detection procedures are placed into a frame quality metric (308). The frame (200), frame quality metric (308), a time stamp (310) and an address (312) are placed into a packet (305) that is transmitted from each base transceiver station to a mobile telephone switching office (104) which matches packets (305) attempting to transmit the same information using the time stamp and selects one frame (300) from the packets (305) for further processing based on the associated frame quality metric (308).

Abstract: A novel and improved method and system for processing multiple instances of data using noise energy based gain control is described. A signal (100) is transmitted from a base station and is received along with associated noise energy by a subscriber unit (104). The non-orthogonal noise energy associated with a signal (100) transmitted to a subscriber unit (104) is measured, and the gain of that signal is adjusted such that the non-orthogonal noise energy is set to a predetermined level. If multiple instances of the signal (100) are received by the subscriber unit (104), the signals are isolated and the non-orthogonal noise associated with each signal is measured separately. In the preferred embodiment the non-orthogonal noise measurement is performed by demodulation (308) of a low energy channel within a forward link signal (100) processed in accordance with code division multiple access signal processing techniques. A reference value is then divided by the result of this demodulation (308) to calculate a control signal (320) which is used to adjust the gain of a signal associated with a second, higher energy, channel within the forward link signal. The reference value may be generated via the use of stored information (319), or via measurement of another signal that has previously been adjusted to a more optimal energy level.

Abstract: A frequency synthesizer (200) which uses a direct digital synthesizer (DDS) (204) to generate a highly accurate periodic signal. The DDS (204) output signal is bandpass filtered utilizing a clean-up phase lock loop (PLL) (214) to produce a spectrally pure reference signal and promote overall fast settling time. A second or primary phase lock loop (220), having a much faster settling time than the first PLL (214), adjusts the frequency of the reference signal generated by the clean-up PLL (214). In one embodiment, the DDS frequency synthesizer (204) has a digital to analog converter (DAC) (206) coupled to the clean-up PLL (214). Another embodiment (300) feeds the most significant bit (MSB) (310) or overflow bit from the DAC accumulator (306) into the "clean-up" PLL (318). Yet another embodiment (400) uses a switching apparatus to bypass the "clean-up" PLL (410) while it is settling on a new frequency.
