摘要： A method is described for generating a M-D CPM waveform as a constant envelope, continuous phase signal capable of conveying a plurality of information symbols per symbol interval. Additionally, it provides for reducing the phase state space of the M-D CPM waveform, for reducing a number of trellis states required for demodulation of the M-D CPM waveform, and for implementing generalized tilted phase decomposition to reduce the cardinality of the phase state space of the multi-dimensional CPM waveform by a factor of 2. A device, computer program product and apparatus are also described.

摘要： The present invention provides a new and unique method and apparatus to generate a sequence of symbols to be transmitted, comprising transmitting a block of symbols having data symbols and redundancy symbols, the redundancy symbols being generated based on the data symbols, a first part of the redundancy symbols being transmitted as a prefix of the block, a second part of the redundancy symbols being transmitted as a postfix of the block and a third part of the redundancy symbols being transmitted as an intermediate part of the block between the prefix part and postfix part. The first part of the redundancy symbols may be generated from the symbols that are transmitted at the end of a data portion of the block, the second part of the redundancy symbols may be generated from the symbols that are transmitted at the start of the data portion of the block, the third part of the redundancy symbols (which are transmitted in the second half of the data portion of the block) may be generated from an entire sequence of non- redundant data symbols that are transmitted in the first half of the data portion of the block and the block may form part of a continuous phase modulation (CPM) waveform that is substantially symmetric-periodic.

摘要： An emulating system comprising a network emulator (152) for emulating multiple test signals. Each test signal is associated with a communication channel of a base tranceiver station having geographic coordinates within the especific geographic area. A channel emulator (154) for processing each test signal using simulation data and generating a channel response signal for each test signal indicating the effect of the simulation data. Wherein the simulation data comprises interference parameters that represent reflective, diffractive, path loss, diffusive and Doppler effect properties created by selectable obstructions over a selectable distance D between the mobile device and the base transceiver station and the vector summation of these properties. A position detection emulator (158) for calculating positional coordinates based on each channel signal gerated and the geographic coordinates of each base transceiver station.

摘要： To reflect advantages of a constant phase modulation waveform, the invention provides a pulse amplitude modulated PAM waveform that is a superposition of Qo=2 L-1 PAM component pulses in each symbol interval such that a significant portion of signal energy over each symbol interval is within the Q 0 PAM component pulses. The present invention distributes most signal energy in one pulse and progressively lower energies in the remaining Q 0 -I pulses of a symbol interval. The Laurent Decomposition is a special case of the present invention, but the present invention exhibits the energy distribution of the Laurent Decomposition in non-binary CPM waveforms and in m?lti-h (binary and non- binary) CPM waveforms, where h is a modulating index. AU energy is distributed among only Q=2 L-1 pulses in each symbol interval, though only Q 0
