Modulated-Carrier Systems TRIZ Cases

Convolution of a bandlimited kernel with sparse spreading sequences shapes signals to resolve silo multi-path interference and noise.

A multi-carrier communication apparatus selects subcarriers with distinct frequencies across base stations to maintain throughput.

A quarter-rate upconverter combines half-sample interpolated and delayed signal streams to process complex data efficiently.

A MediaFLO receiver estimates carrier frequency offset using dynamic Time Domain Interpolation filters selected via correlation lookup tables.

Dynamic PUCCH carrier switching maps reference cell slots to target cells, reducing overlapping slot complexity in mixed numerology scenarios.

Segmenting HARQ-ACK codebooks into groups reduces configuration complexity, enabling reliable multi-TRP data transmission without excessive signaling overhead.

Layer 1 and Layer 2 signaling paths transmit positioning reference signal measurements, reducing latency compared to traditional Layer 3 reporting methods.

Transforms multiple system symbols into one positioning symbol to extend cyclic prefix length.

Block-based overlap-and-save correlation compensates for laser frequency drift in chirped-pulse distributed acoustic sensing systems.

Encoding the reference signal with a lower modulation and coding scheme than the data channel mitigates phase noise in millimeter wave frequencies.

A compensating circuit dynamically generates carry values to estimate truncation errors in reduced-width multipliers.
