Flexible precoding is proposed as a technique to improve the signal to noise ratio in a wireless local loop over the “last mile” of the telecommunications network to the consumer. Flexible precoding pre-equalises the transmission signal by performing a stable feedback filtering operation. Performance results show that flexible precoding outperforms a fractionally spaced equaliser over quasi static and slowly varying continuous small cell mobile channels at high transmission bit rates. Hence the quality of service or capacity of the wireless local loop can be maximised.
