Abstract
Certain aspects of the present disclosure relate to a method for modulating single carrier signals using constant envelope 2-CPM modulation and quasi-constant envelope filtered continuously rotated pseudo-PSK modulation in a wireless communication system.
Claims
exact text as granted — not AI-modified1 . A method for communication, comprising: encoding a binary data stream using one of a continuously rotated differential pseudo BPSK (πh 2 -DPBPSK) encoding and a continuously rotated generalized differential pseudo QPSK (πh 4 -GDPQPSK) encoding; and filtering the encoded binary data stream to produce a quasi-constant envelope modulated signal.
