In an uplink scenario, to decrease the multi-user interference (MUI) induced by practical rectangular pulses, our method exerts a new interleaved approach to allocate non-overlapping delay-Doppler (DD) bins to the distinct user terminals (UTs) without any GB among them. A zero-padding (ZP) scheme is employed to cope more with the MUI and reduce the complexity of the data detection process. Additionally, we utilize subspace pursuit (SP), a compressed sensing technique, in conjunction with a unique pilot pattern extracted from the data frame structure for channel estimation. By preserving the estimation quality, this method can reduce the system's peak-to-average power ratio (PAPR) without necessitating an increase in pilot overhead. We also employ a two-stage feedback-oriented scheme to adapt the block linear-minimum mean square error (BL-MMSE) detector for data detection. Our method, which we evaluated through simulations, can provide notable results regarding the signal-to-noise ratio (SNR) and bit-error-rate (BER).
