摘要： A receiver for a wireless communication device provides a dual path receiver receiving first and second protocol-agnostic, uncorrelated receive signals simultaneously. The dual path receiver generating first and second offset IF signals from the simultaneously received first and second protocol-agnostic, uncorrelated receive signals. The receiver utilizes at least one converter for converting the first and second offset IF signals into at least one serial synchronous interface (SSI) signal representing the spectrum at IF. At least one processor receives the at least one SSI signal and applies parallel processing paths to demodulate the at least one SSI signal into separate baseband signals. The processor provides interference detection of, and level control for, the first and second offset IF signals.

摘要： A multi-carrier modulation communications system and method (100) for providing channel estimation that uses a transmitter for inserting pilot symbols in a digital multi-carrier modulated radio frequency (RF) signal and a receiver for receiving the pilot symbols in multi-carrier modulation RF signal. In order to provide channel estimation the receiver detects (101) channel power gains from a plurality of designated pilot symbols and calculates (103) both a speed parameter (S) and a multi-path parameter (M) for the channel receiving the pilot symbols. A channel model is then defined (105) based upon the speed parameter and multi-path parameter value and a predefined set of pilot coefficients is chosen (107) that substantially matches the channel model. The resulting set of pilot coefficients is then utilized (109) for optimizing pilot symbol interpolation.

摘要： The present invention switches from the TDMA non-scan channel to an RF carrier signal frequency of the scan channel. If the scan channel is unmarked, performing an inspection of activity on the scan channel in order to determine whether activity on the scan channel is addressed to the radio device, and marking the scan channel when activity on the scan channel is not addressed to the radio device. Determining whether the scan channel is active in response to determining that the scan channel is marked, unmarking the scan channel in response to determining that the scan channel is not active, and switching to the RF carrier signal of the TDMA non-scan channel, wherein the timing of the switching between the RF carrier signal frequency of the scan channel and the RF carrier signal of the non-scan channel is dependent on the timing of the designated slots of the non-scan channel.

摘要： A method for maximizing intermodulation interference protection during a handoff between radio cell sites (300) includes scanning a plurality of radio channels (302) and measuring the signal power (307, 315) for at least one of the radio channels. One or more receiver attenuators (313) are then set based on the detection of intermodulation (IM) interference of the measured channel. The attenuators are then scaled (311) based on the degree of IM interference. If the attenuators cannot mitigate this interference below some predetermined level, the radio channel is changed (321) and the process begins again to ensure a high quality of communication with a cell site.

摘要： Encryption synchronization (e-sync) is maintained between a transmitter (104) and one or more receivers (102) in a multi-modulation TDM system (100) where information is communicated in slots (402) comprising a slot header (404) and one or more data blocks (406), and wherein the data blocks are eligible to be encoded at different modulation rates thereby creating a likelihood of different numbers of blocks in different slots. The receiver and transmitter employ respective encryption elements (200, 300) comprising e-sync shifter elements (202, 302) and encryption algorithm blocks (204, 304). The e-sync shifter element provides an e-sync signal defining an encryption state vector to the encryption algorithm block and is operable to advance the encryption state vector (in the case of the receiver) according to a number of received bits plus a variable number of bits. The variable number depends on the number of bits within a block, the maximum number of blocks that could be within a slot and the actual number of blocks within the slot.

摘要： A method for the selection of forward error correction (FEC)/constellation pairings (800) for digital transmitted segments based on learning radio link adaptation (RLA) including formatting a packet transmission having a predetermined number of information bits (801). The packet is then split into a plurality of segments (803) where an RLA is used (805) to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping (807) at a rate selected by the RLA. The segments are then formatted into packet blocks (809) and transmitted in blocks that form a time slot at a constant symbol rate.
