The atomic vectors of a finitely generated vector space C over a field F are characterized for C a subspace of the product vector space ? = ∏ i =1 n ? i over F. For finite fields, the minimal trellis diagram for mixed-codes is determined, and this provides the L-section minimal trellis diagram for linear codes. As an example, an extremely simple yet(More)
This report provides an introduction to the problem of analyzing the performance of satellite on-board regenerative repeaters. Two speci c group demodulator architectures are discussed: one based on a polyphase network followed by an FFT processor, and the other based on a chirp Fourier transform implemented using surface acoustic wave (SAW) devices. Due to(More)
