If you are familiar with mobile communication, WCDMA and OFDAMA are the physical layer technology used for UMTS (3G) and LTE networks. LoRa is based on chirp spread spectrum modulation, which is similar to FSK (Frequency Shifting Keying) modulation but it increases the communication range significantly.
Spread spectrum technology has become a key building block in cordless, cellular, WLAN systems, and more. This tutorial provides an overview of spread-spectrum and its popular variants direct-sequence and frequency-hopping.

This paper proposes a new approach in chirp modulation spread spectrum (CMSS). A good selection of the parameters of the linear chirps, which are used in chirp modulation, combined with antipodal signaling significantly reduces the multiple access interference. (MAI) even for small time-bandwidth products. This makes.

Therefore, the receivers for spread-spectrum schemes have to convert the received wideband signals back to their original narrowband waveforms before detection. This process generates a certain amount of processing gain that can be used to combat radio jamming and interference. We will describe and discuss in detail.

If the PRN acts as an on/off gate to the transmitted signal, this is a time-hopping spread-spectrum technique (THSS). There is also the "chirp" technique, which linearly sweeps the carrier frequency in time. One can mix all the above techniques to form a hybrid spread-spectrum technique, such as DSSS + FHSS.
