Title: Method and apparatus for reducing aliasing in cascaded filter bank
Inventor: SCHULLER GERALD DIETRICH
IPC: G10L19/02
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for reducing aliasing between neighboring subbands in cascaded filter banks. SOLUTION: The magnitude response and phase of an alias reduction filter bank are similar with the magnitude response of a synthesis filter bank of the first stage filter bank. The alias reduction filter bank filters and adds signals from a set of M2 subbands from the M1 subband of the first stage filter bank. High-frequency resolution is obtained after an alias reduction stage by an analysis filter bank. The signals from the subbands are first supplied to the alias reduction filter bank, to reduce the aliasing. When the first stage filter bank is the modulated uniform filter bank having M1 bands, the stage of alias reduction has M2 bands and an alias cancel is possible, the alias reduction filter bank has a frequency which is scaled by the sampling rate M1/M2.  However, it is necessary for the alias reduction filter bank to have a frequency response similar to that of the synthesis filter bank of the filter stage.

Title: Demodulator and wireless device
Inventor: KOBAYASHI HIDEYUKI
IPC: H04L27/22
Filed: 2001-06-01
Abstract: PROBLEM TO BE SOLVED: To provide a demodulator that automates the inversion/noninversion of a carrier phase in a local phase inverter and to provide a wireless device. SOLUTION: A local phase control circuit logically calculates phase setting for inverting/noninverting the carrier phase that may be caused by a hierarchical relation between the frequency of a signal received by the transmission/reception common local system and the frequency of a local signal based on a pseudo lock detection output, an asynchronous detection output of a recovered carrier wave, and a frame synchronization detection output. Then the local phase control circuit controls the inversion/noninversion of the carrier phase according to the result of calculation.
