摘要： A system and method are provided for supplying a frequency-smoothed communications training signal. The method generates a frequency-smoothed unbiased training signal in a quadrature modulation transmitter. The frequency-smoothed unbiased training signal includes a plurality of pilot signal products, where each pilot signal product includes complex plane information represented by a reference frequency subcarrier, multiplying complex plane information represented by mirror frequency subcarrier. The sum of the plurality of pilot signal products is equal to zero. The method supplies the frequency-smoothed unbiased training signal so that it may be transmitted within a single symbol period. System and methods are also provided for using a frequency-smoothed training signal in the calculation of a receiver channel estimate.

摘要： An orthogonal frequency division multiplex (OFDM) transmitter may adaptively load each sub-carrier, buffering less than an OFDM frame in order to reduce hardware requirements and latency. The transmitter may use feedback information from the receiver regarding the quality of the sub-carriers. In addition, combining repetition and puncturing to achieve a desired date rate per class further reduces hardware by simplifying or even eliminating an interleaver. Additional mitigation and even performance enhancement techniques are incorporated to address inter-class boundaries within an OFDM frame, such as introducing transition classes. Channel state information may be reported in various formats including full bitmap, changed subchannels, and reported bad subchannels.

摘要： A system and method are provided for using frequency domain spreading to generate real signals in the time domain. The method supplies a first complex frequency domain symbol (α) and a second complex frequency domain symbol (αi), and maps (α+jαi) onto a subcarrier (+f). Further, (α−jαi)* is mapped onto a mirror subcarrier (−f). The mappings are converted into a complex time domain symbol carrying α and jαi in a single inverse fast Fourier transformation (IFFT). The real component of the complex time domain symbol (α) is initially supplied, and subsequently supplied is an imaginary component of the complex time domain symbol (αi). The real symbol component (α) is supplied by carrying α on the subcarrier (+f), and carrying (α)* on the mirror subcarrier (−f). The imaginary symbol component αi is supplied by carrying αi on the subcarrier (+f), and carrying (αi)* on the mirror subcarrier (−f).

摘要： A development and runtime framework for applications that execute in real-time operating systems. Application development is enhanced through simple instructions that allow a programmer to declare functions and sets of functions as tasks and supertasks, respectively, and manage the execution of functions, tasks and supertasks with priorities. A compiler or pre-processor provides tools for generating the code for tasks and supertasks, and the management code for managing execution. Function calls may be made directly to functions within supertasks via respective entrypoints, and the tasks are managed based on the functions being invoked. Within a supertask, a higher priority function may be runnable while a lower priority function of that supertask is suspended. A cookie is used to recognize when a register update for a supertask may be omitted, enabling more efficient context switching.
