Subband coding of cyclostationary signals with static bitallocation

摘要

We consider the optimal orthonormal subband coding of zero meannwide sense cyclostationary signals (WSCS), with N-periodic second ordernstatistics. An M-channel uniform filterbank, with N-periodic analysisnand synthesis filters, is used as the subband coder. A static bitnallocation scheme is used. An average variance condition is used tonmeasure the output distortion. The conditions for maximizing the codingngain parallel those for the case when the signals are wide sensenstationary (WSS) and the analysis and synthesis filters and the bitnallocation time invariant
