Patent ID: 7916694

Claim:
A method of transmitting a plurality of Orthogonal Frequency Division Multiple (OFDM) symbols in a block transmission system of a communication network, the block transmission system being a frequency reuse system, the method comprising: a. encoding the plurality of OFDM symbols; b. modulating a phase and a magnitude of the plurality of OFDM symbols with a low-ripple filter reducing a peak to average power ratio (PAPR) of the plurality of OFDM symbols, wherein the plurality of OFDM symbols are modulated such that a conversion of the modulated OFDM symbols from a time domain to a frequency domain gives a positive modulus, wherein the positive modulus is ensured by constraining a number of taps of the low-ripple filter; and c. converting a plurality of modulated OFDM symbols from a digital form to an analog form, wherein the plurality of modulated OFDM symbols correspond to the plurality of OFDM symbols.
