Multiplex Code Generation TRIZ Cases

Optimized orthogonal transmitter coding extends maximum unambiguous Doppler shift in PMCW MIMO radar systems.

A multiplexer generates encoded CPM sequences from stored PN codes using a counter.

Neural networks learn spread codes to reduce cross-correlation values, resolving detection performance drops caused by high device density.

Non-uniform amplitude values in a CDMA code book reduce peak-to-average power ratio while maintaining average energy per chip.

Prototype function shaping replaces guard intervals in multicarrier signals, resolving spectral efficiency trade-offs.

Inverting original code bits increases spreading code randomness, reducing synchronization time while maintaining confidentiality.

Dividing sequences into dedicated pools reduces interference between multiple user equipment devices sharing the same uplink resource allocation.

Flexible processing streams allocate users across multiple antennas, reducing hardware resource consumption and latency in remote radio head systems.

A terminal apparatus generates a Zadoff-Chu sequence with an extended length matching allocated subcarriers to support bandwidth expansion.

Generalized Golay sequences enable flexible code length generation, reducing multiple-access interference in DS-CDMA systems.

A random phase multiple access interface transmits data using unique pseudo-noise codes and chip offsets to separate signals without orthogonal code coordination.

Multi-stage sequence generation segments scrambling and interleaving processes to reduce multi-user interference while controlling system complexity.

An algebraic structure constructs Golay complementary sets with elastic lengths, reducing storage hardware costs compared to power-of-two limitations.
