OTFS leverages delay-Doppler domain sparsity to reduce channel training overhead, mitigate aliasing and ISCI, and offer higher spectral efficiency than OFDM in fast-varying, doubly-dispersive wireless channels.

This story was originally published on HackerNoon at: https://hackernoon.com/why-first-order-channel-models-matter-for-high-mobility-wireless-systems.
A clear explanation of why OFDM’s LTI models fail in fast-changing channels and how first-order and delay–Doppler models improve accuracy and performance.

The article explains why OFDM’s traditional LTI channel model collapses in high-mobility environments, showing how first-order Taylor approximations and delay–Doppler domain modeling extend coherence time, reduce estimation overhead, and yield more accurate representations of rapidly varying wireless channels.

Myriad became the first prediction market integrated directly into Trust Wallet's new Predictions feature, giving it access to 220 million users. The integration comes after Myriad reached $100 million in trading volume with 400,000 active traders. Trust Wallet plans to add Kalshi and Polymarket to create an aggregated prediction market hub. The move reduces friction for users while positioning wallets as full-featured financial platforms beyond basic asset storage. Success depends on sustained engagement rather than event-driven volume spikes.

Ragsdale: The modern workplace depended entirely on human awareness to move work forward. He says this dependence on human attention was the opposite of autonomy. Ragsdale spent more than twenty five years building companies, designing systems, and using each environment as a research laboratory for enterprise autonomy.
