    摘要: The present invention relates to a method of wirelessly transmitting and receiving audio digital signals of the type having a first plurality of blocks with each block having a second plurality of frames, with each frame having a third plurality of subframes, with each subframe having a preamble and a binary data. The method efficiently transmits and recomposes the digital audio signals by searching for the preamble associated with a subframe, which is the first subframe of a frame, with the frame being the first frame of a block, and then transmitting wirelessly only the binary data of each subframe, in each frame, in each block thereafter. In a preferred embodiment, the protocol for the transmission of data calls for each data packet that is transmitted to consist of 512 bytes. The data packet transmitted by the transmitter must be acknowledged by the transmission of an acknowledgement (ACK) packet from the receiver. In the event, the data packet is not received and/or the ACK packet is not received, and transmission must recommence, synchronization is accomplished by the retransmission of data packet immediately after the preamble of the first subframe of the first frame of a block.

    摘要: A spread-spectrum preamble synchronization peak detection system performs multiple statistical tests based on instant and time-averaged channel condition measurements to identify the synchronization peak. In a normalized peak-to-average test, a peak-to-average ratio measurement is normalized by a signal-to-noise ratio measurement to form a new statistical measure which effectively eliminates the impact of the wide dynamic range of the signal-to-noise ratio of the received samples. A transition SNR test is used to eliminate potential false alarms caused by spurious PARN peaks during the transition period at the onset of preamble arrival. Code-phase aligned time-averaging is used to estimate the signal and noise levels over a sliding window. The code-phase alignment of samples effectively separates signal and noise samples in the averaging process, and resulting in more accurate signal and noise measurements. In estimating noise levels, the system takes multi-path interference into account by excluding both the peak signal and the side-lobe signals caused by multi-path wireless channels, resulting in more accurate estimation of noise level.

    摘要: A system for synchronizing a spreading sequence transmitted during a plurality of time slots includes a plurality of communication stations. Each communication station includes: (a) a control unit; (b) a spreading sequence unit for originating the spreading sequence; (c) at least one of a transmitter and a receiver; (d) at least one delay unit responding to the control unit for imparting a first delay to the spreading sequence presented to the transmitter unit and responding to the receiver unit for imparting a second delay to the spreading sequence presented to the receiver unit; and (e) a synchronizing sequence generator coupled with the transmitter unit. The synchronizing sequence unit in a first station presents a synchronizing sequence for transmission accompanying spread information transmitted during selected time slots. A receiver unit in a second station employs the synchronizing sequence in cooperation with the spreading sequence for despreading received spread information.
