- determining a pseudo random sequence to modulate the cyclic prefix, wherein the modified cyclic prefix consists of a sequence of symbols modulated with the pseudo random sequence
2. claims: 4-6
- identifying a restricted modulation and coding scheme MCS for the ranging measurement frame, wherein the ranging measurement frame is transmitted according to the restricted MCS
3. claims: 7-17, 22-24
- encrypting a channel estimation training sequence of the ranging measurement frame, wherein the transmitted ranging measurement frame includes the encrypted channel estimation training sequence
4. claims: 20, 21, 30
- modeling the channel as a finite impulse response FIR filter and determining a system of equations based at least in part on the FIR filter
1.
As all required additional search fees were timely paid by the applicant, this international search report covers all searchable claims.
2.
As all searchable claims could be searched without effort justifying additional fees, this Authority did not invite payment of additional fees.
