摘要： An improved multicarrier modulation system and method is introduced which has the advantages of both isotropic orthogonal transfer algorithm orthogonal frequency division multiplexing (IOTA OFDM) and scalable advanced modulation (SAM). The invention reduces adjacent channel interference (ACI) in the multicarrier modulation system used in multicast systems by generating (2601) a spectrally efficient modified pulse for multicarrier modulation and then adapting (2605) the pulse at the edge of the subchannel for reducing the ACI product by the total multicarrier signal (2607). This BTRRC OFDM (2607) is an Offset OFDM with BTRRC pulse (2605) while the prior art RRC OFDM (604) is an Offset OFDM with RRC pulse (603). BTRRC OFDM has characteristics similar to RRC OFDM and has better power efficiency in simulcast or Nakagami fading environments where there is a timing error. Thus, BTRRC OFDM is desirable to substitute SAM in a simulcast environment.

摘要： An improved multicarrier modulation system and method, which has the advantages of both isotropic orthogonal transfer algorithm orthogonal frequency division multiplexing (IOTA OFDM) and scalable advanced modulation (SAM), is introduced. The invention is root raised cosine (RRC) OFDM using the most spectrally efficient RRC filter without sacrificing the compact subchannel spacing of OFDM. The invention further provides an adjacent channel interference (ACI) suppression scheme and a modified RRC for better suppressing ACI of RRC OFDM. The ACI suppression scheme can also be applied to SAM with the modified RRC and to IOTA OFDM with a modified IOTA. The invention greatly improves a major problem of conventional OFDM namely ACI due to the use of a wide subchannel filter. Thus, the invention allows OFDM to meet even the strictest ACI requirements, which was not possible by using a conventional raised cosine windowing method.

摘要： A method for controlling peak-to-average power ratio prior to amplification by a power amplifier is provided. The peak sample of a signal is predicted, window length is adjusted based on the peak width around the peak sample or subcarriers used to transmit the signal, and the window is subsequently used to clip the samples. A peak suppression window may be applied prior to predicting the peak sample when a set number of samples exceed a predetermined threshold. Window clipping may be deactivated if interference and throughput of the power amplifier is detrimentally affected. A pulse shaping filter may be optimized based on the window clipping to control transmitted signal characteristics. Various thresholds used in the prediction may be initially based on system design and power amplifier linearity and then dynamically adjusted based on an estimation of active subcarriers or of interferers present in the communication system.

摘要： A system and a method to enlarge the minimum signal of a linear modulation signal (115) including multi-carrier modulation, such as Scalable advanced Modulation or Orthogonal Frequency Division Multiplexing, are disclosed. A minimum enlarger (120) exploits a simple amplitude limiter (220) so as not to interfere with an existing peak suppression scheme. The amplitude limiter (220) enlarges local minimum amplitude values to a predetermined minimum amplitude threshold if the local minimum amplitude values are less than the predetermined minimum amplitude threshold. While the amplitude limiter (220) adjusts the local minimum amplitude values in the linear modulation signal (115), the phase of the linear modulation signal (115) is maintained. The conditioned linear modulation signal (125) increases the efficiency of a linear power amplifier (130). The spectral change of the linear modulation signal due to the disclosed scheme is negligible because the adjusted signal power is negligible.
