Embodiment Construction
[0078]In the following, embodiments providing compression and decompression of complex-valued OFDM signals, suitable for use with the Common Public Radio Interface (CPRI) of radio base stations conforming to UMTS LTE / LTE-A will be described. However, the complex-valued OFDM signal compression and decompression can also be used for other applications.
[0079] A time-domain complex-valued digitized discrete OFDM signal with N data symbols, defined over the time interval t ∈ [0, NT] and transmitted through N different sub-channels, can be expressed as where A i Represents a complex-valued baseband modulation symbol. If the OFDM signal is sampled at time t = nT, the discrete complex-valued OFDM samples can be expressed as n=0,1,...,N-1, where s n is the sum of independent and identically distributed (i.i.d.) random variables. According to the central limit theorem, when the number of subcarriers tends to infinity, s n converges to a zero-mean stationary Gaussian random pro...
