Abstract
The new STM-1 signal format can be carried advantageously by high-capacity digital radio systems by making use of cochannel operation. This can be implemented in an economical way by fully exploiting the capabilities of silicon VLSI technology. A fully digital adaptive transversal filter IC was developed which can be used not only in the time-domain equalizer, but also in a crosspolarization interference canceler. This offers a very economical solution for a cochannel system providing twice the channel capacity. Due to synchronization of carriers and the timing of both orthogonal polarized signals the baudspaced transversal filter structure of the VLSI circuit enables superior performance both for the equalizer and for the canceler operation. The theoretical concepts behind the system are presented and experimental results are discussed.
