Open-source coursework from platforms like MIT OpenCourseWare (OCW) or NPTEL.
Chaudhari describes the book as a collection of answers to the many "whys" he encountered while studying works by industry "grandmasters" like Fred Harris and Michael Rice.

If you're looking for a free, legal resource to learn wireless communications from the ground up, I can suggest authoritative alternatives (e.g., MIT’s 6.02 notes, or “Software-Defined Radio for Engineers” by T. Collins ). Would you like those? Would you like those
Digital modulation maps bits to waveform symbols. BPSK uses two phases (0°, 180°) to represent bits 0 and 1; its symbol error rate over AWGN with energy per bit Eb and noise spectral density N0 is Pe = Q(√(2Eb/N0)). Higher-order QAM trades power/complexity for spectral efficiency but requires higher SNR to maintain the same error rate.
